MythBusters (2011 yilgi mavsum) - MythBusters (2011 season)

Keyin juftlik bir-birlarining niqobini va kiyimlarini, bir-birlarining tana shakliga mos ravishda to'ldirilgan holda, kiyib olishdi. Ular oltita ko'ngillilarni (shou muxlislari bo'lgan) ularga yaqinlashishga yo'naltirishdi, ular 90 metrdan 5 metrgacha tugashdi, shu bilan bog'liq bo'lmagan topshiriq yordamida testning mohiyatini yashirishdi. Uchtasi "Jeymi" bilan, uchtasi "Adam" bilan ishlagan va oltitasi ham aldovni aldovni tezda gapirishlari bilan aniqlagan. Keyin yana olti nafar ko'ngilli niqoblangan mezbonlar gapirmagan testda qatnashdi; yolg'onchi bilan yuzma-yuz kelguncha ularning hech biri hech narsadan shubhalanmagan.

Jeymining tashqi qiyofasi va o'zini tutishi bilan yaxshi tanish bo'lgan Grant va Kari ham xuddi shunday sinovda qatnashishdi, "Jeymi" shkafi nozik o'zgarishlarni chalg'ituvchi narsa sifatida. Ularning ikkalasi ham uni 5 metr masofada bo'lmaguncha uni soxta deb bilishmagan, ammo Kari 70 metr balandlikda shubha bildirgan. Odam va Jeymi afsonani hiyla-nayrang qanday sharoitda amalga oshirilganiga qarab ishonchli deb tasnifladilar.

Jamoa o'qlarni to'xtatib, o'z kuchlarini quvnoq kayfiyatda o'tkazishga majbur qilish uchun temir yo'llarga temir plitalarni qo'shib qo'ydi. Ushbu o'zgarishni amalga oshirgandan so'ng, ular boshqa kiyik shilimshig'ini sinab ko'rishdi va uni 1,5 dyuymga aylantirishga muvaffaq bo'lishdi; an Armalit AR-50 miltiq uni 8 dyuymga burdi va plitalardan birini o'chirdi. Shu payt, jamoa afsonani e'lon qildi va natijalarni takrorlashga kirishdi, Tori ishqalanishni kamaytirish uchun quvnoq gumbazning yotoq tizimini qayta ishlab chiqdi va Kari va Grant o'qlarni to'xtatuvchi plitalarni biriktirdi. Ular nihoyat qurilmani doimiy ravishda 12 o'lchovli kiyik shilimshiqlari oqimlari bilan ushlab turishga muvaffaq bo'lishdi .416 Barret miltiq olovi.

To'liq miqyosdagi sinov uchun ular filmda ko'rinib turganidek, Jeyson Bornning kvartirasining nusxasini qurdilar va tushdi mashinasi, jurnal va gaz ta'minotini o'rnatdilar. Sahnani filmdan to'liq takrorlagan ularning birinchi urinishi hech qanday samara bermadi, chunki gaz kontsentratsiyasi portlovchi darajaga yetguncha jurnal butunlay yonib ketdi. Ikkinchi sinovlarida ular xonaning o'rtasiga o't ochadigan log qo'yib, gazning asta-sekin portlovchi darajaga ko'tarilishiga imkon berishdi. Aralash oxir-oqibat alangalanib, kichik portlashni keltirib chiqardi, u qisman devorni portlatib yubordi va shiddatli yong'inga yo'l ochib, aksariyat mebellarni yo'q qildi. Adam va Jeymi afsonani buzib e'lon qilishdi va gazni yoqishdan oldin, gazni va havoni yaxshilab aralashtirish uchun 9% konsentratsiyaga (yonuvchanlik markazining markazi) erishish uchun etarli miqdordagi metanni va bir qator fanatlar va diffuzor shlanglarni ishlatdilar. ixtisoslashtirilgan qurilma bilan aralashtiring. Bu safar ular bitta devorni portlatib, kvartirani yoqib yuborishdi.

Grant va Tori tashrif buyurgan a NASA tadqiqot markazi va burg'ilashni yuqori shamol tezligini va samolyotning kruiz balandliklariga xos sovuq haroratni takrorlashga mo'ljallangan tunnelga joylashtirdi. Tualetni birdaniga tashlab yuborishganda, suyuqlik tezda shamolda atomizatsiyalashdi va fyuzelyajda muzlash uchun faqat ingichka plyonka qoldi. Biroq, sekin oqish muzning katta massaga aylanishiga imkon berdi, u burg'ilash qurilmasi 12000 futgacha "tushguncha" bo'shashmadi.

Bunday qismning erga qulab tushishida omon qolish qobiliyatini aniqlash uchun Kari va skydiverver shu balandlikka uchib ketishdi, 35 funtlik muz blokini samolyotdan uloqtirib tashlashdi va Grant va Tori uni kuzatib borishganda orqasidan sakrab chiqishdi. zamin. Blok qulash yoki zarba paytida sezilarli darajada erishi yoki shikastlanishiga olib kelmadi, natijada jamoani afsonani tasdiqlangan deb e'lon qildi, ammo natijaga erishish uchun bir vaqtning o'zida bajarilmasligi kerak bo'lgan kafolatlar soni ehtimoldan yiroq.

A filmining kadrlarini o'rganib chiqqandan so'ng reyhan suv ustida ishlaydigan Odam va Jeymi oyoq harakatlarini takrorlash uchun alohida poyabzal dastgohlari qurishga qaror qilishdi. Ular mashq qilgan akrobat va gimnastikachi Jessika Fortunatoni chaqirishdi va uni burg'ilash uskunalarini sinab ko'rishdi: Odamning oyoqlari platformasi va uzun dumi bilan, Jeymi esa botiq oyoq chashkalari va ustun ramkasida. U suvsiz turolmadi, yordam berilmasa ham, burg'ilash vositalaridan birini ishlatsa ham.

Shu payt Adam va Jeymi afsonani buzib e'lon qilishdi va natijalarni takrorlash uchun suv osti ko'prigini qurishdi. Kamuflyajdan so'ng va kamerani ma'lum bir burchakka o'rnatgandan so'ng, ikkalasi ham ko'prikning uchidan chiqib ketguncha sirt bo'ylab yugurish imkoniyatiga ega bo'ldilar.

Ushbu devor effektlarini yo'q qilish uchun Adam va Jeymi suzish havzasining pastki qismiga joylashtirish uchun 16 dyuymli 16 metrli pufakchani qurishdi. Qurilma suzib yurmasligi uchun ular og'irlik qo'shgandan so'ng, Odam Atrof hovuz bo'ylab suzib o'tishga va ko'piklar orasidan o'tishga harakat qildi. Safar 25% quvvat bilan qiyin, 100% esa imkonsiz bo'ldi. Adam va Jeymi afsonani ishonchli deb tasnifladilar, ammo kutilganidan boshqacha sabab - uning cho'kib ketishiga olib keladigan zichlikning pasayishi emas, balki suzuvchini ushlab turadigan suv oqimlari.

Mifni buzilgan deb e'lon qilib, jamoa turli xil portlovchi moddalar va joylashtirish texnikasi bilan kichik hajmdagi sinovlarni o'tkazdi. A TNT Magistralga tushirilgan zaryad portlash nuqtasida uni maydalab tashlagan bo'lsa, an ANFO Yog'och donalari bo'ylab kesilgan oluklarga qo'yilgan zaryad ma'lum darajada bo'linishga olib keldi.

So'nggi to'liq miqyosli sinovdan so'ng, jamoa 100 metrni tanladi Ponderosa qarag'ay va 25 funt ANFO bilan jihozlangan, yadro yonida kesilgan oluklarga yotqizilgan. Olingan portlash daraxtni yuzlab bo'laklarga bo'lib tashladi.

Adam va Jeymi bir nechta keng ko'lamli torpedalar qurishdi, ularni ko'lga olib borishdi va qirg'oqdan 800 fut (244 m) masofada maqsadli kemani o'rnatishdi. Ikkala aniqlik sinovi - avval to'liq qo'zg'aluvchan zaryad bilan (raketa dvigateli sifatida), so'ngra kamaytirilgan bilan - torpedani havoga chiqarib yuborish va maqsadni to'liq o'tkazib yuborish. Yuklarni etkazib berish bo'yicha keyingi ikkita sinovda ular bog'lash vositasi yordamida torpedani boshqarishdi, ammo ular kemani qirg'oqdan 61 fut masofaga ko'chirgandan keyin ham zarba bera olmadilar. Va nihoyat, ular bog'ichni olib tashlashdi va raketa kuchini yanada kamaytirdilar, bu ularga kemani urib, yoqib yuboradigan yuk bilan yoqib yuborishga imkon berdi. Ular afsonani ishonchli deb tasnifladilar, chunki ular jangovar qurilmada foydalanilganligi to'g'risida hech qanday ma'lumot topa olmadilar.

MythBusters shampan sharbatli qurol

Mahalliy sharob zavodiga tashrif buyurib, sharob shishasi qo'ziqorini nimaga urishi mumkinligi haqida bilish uchun Build Team do'konda sharob / shisha turi va haroratini tekshirishga qaror qildi. Ular har bir shishani bruska ustiga qo'yishdi va har bir qo'ziqorin uchib o'tgan masofani o'lchashdi. Shishalarni sovutish haroratning kattaroq o'zgarishi natijasida yuqori bosim ko'tarilishi tufayli masofani oshirdi. Tinch va ko'pikli vinolarning eng yaxshi ijrochilari bo'ldi Risling (30 fut (9 m)) va Shampan (50 fut (15 m)), mos ravishda, shampan shishasiga quyiladigan yuqori bosim tufayli farq bilan.

To'liq miqyosli sinov uchun jamoa yarim tirkamaga 1000 shisha shampan va ba'zi Risling yukladi, so'ngra uni yoqib yubordi. Uchalasi ham portlashdagi mantarlarning ovozi pulemyotlarga yoki fişeklarga o'xshaydi, deb kelishib oldilar; ammo, hech bir tirnoq 50 metrdan uzoqqa uchmadi. Ushbu natijaga asoslanib, jamoa afsonani buzilganligini e'lon qildi, so'ngra a-ni o'rnatdi Gatling qurol - butilkalarni bruska ustiga aylantirish va tirnoqlarini to'g'ridan-to'g'ri uchirish uchun moslama. Yong'in kostyumi kiygan Grant, burg'ilash qurilmasi oldida turib, bir nechta to'g'ridan-to'g'ri zarbalarni oldi.

Yelkanlar kichikroq va tezroq tirgaklar bilan havo suzib yurib, atrofga aylana boshlagach, arava orqaga burildi. Katta suzib yurish va ko'tarilgan fanning uyg'unligi aravani oldinga siljishiga olib keldi; Grant bunga suzib yurish suyanchiqning orqaga qaytarilishining bir qismini "aks ettirishi" natijasida kelib chiqqan deb taxmin qildi (aslida yelkanga urilgan havo tashqi tomonga, tepa, pastki va yon tomonlarga qarab oqadi, lekin yelkanning egriligi tufayli oqim bir oz orqaga burilgan). Skeytbordga o'rnatilgan kichik reaktiv dvigatel bilan va yong'inga chidamli suzib yurishdan foydalangan holda kattaroq ko'lamli sinov ham xuddi shunday samara berdi.

Va nihoyat, jamoa ko'lda to'liq ko'lamli sinovni o'rnatdi botqoq qayiq 40 ot kuchiga ega fan bilan. Qayiq fanati orqaga qarab, yelkan ishlatilmay turib, 20 milya (32 km / soat) tezlikka erishdi. Ventilyator orqaga qaytarilib, yelkan ko'tarilgandan so'ng, jamoa muxlisning maqsadini aniq belgilab qo'ygandan so'ng, qayiq 3 milya (5 km / soat) tezlikda oldinga yurdi.

Barcha testlarda kvadrat suzib yurishning asosiy dizayni ishlatilgan.

Keyin Jeymi qisqa trubkadan hubcap bilan bir xil diametrda yangi uchastka yasadi, bo'sh uchi esa pichoqlarga o'ralgan. Ushbu dizayn Odam Atoning korpusini yirtib tashladi, bitta g'ildiragini otib tashladi, ikkinchisini esa chetidan tortib oldi va mashina o'z shassisida o'tirdi.

Keyinchalik, Adam kapotiga qurol va to'liq o'q-dorilar saklagichini o'rnatdi va orqa oynasini olib tashlagan holda nishonga olingan mashinani boshqargan Jeymini quvib chiqardi. U orqa tomonni jumboq bilan ishlay oldi va Jeymining boshi va o'tirgan joyiga mahkam o'rnashgan joy bilan bir necha bor urdi; Maqsadga o'rnatilgan sinovda u juda qisqa vaqt ichida juda ko'p xitlarni qo'lga kiritdi, chunki Jeymi yugurishni erta tugatishga chaqirdi.

O'zlarining kadrlarini qayta tekshirgandan so'ng, guruh aylanayotgan o'q bo'lishi mumkin bo'lgan ovozni eshitdi. Qish kelgach, ular Kapsl ko'liga tashrif buyurishdi Syerra Nevada va keyingi ish uchun uning muzlagan yuzasida maqsadli joyni qazib oldi. Sinov hech qanday natija bermadi, chunki ular maqsadli saytning markazini oldinga yo'naltirish o'rniga orqaga qarab rikoshet qilishga imkon berishdi. Jamoa ushbu so'nggi sinovlardan o'qlarni yon tomonida aylanayotganini aniqladi va bu ularni afsonani tasdiqlashiga olib keldi.

Keyin ular Deyv otashining standart masofadagi bo'sh patronlarini turli masofalardan tomosha qilishdi va 200 soatdan (183 m) o'tgach uning tumshug'i miltillaganini ko'ra olmasliklarini aniqladilar. U og'irroq porox yuklari bilan Gollivud uslubidagi bo'shliqlarga o'tsa, ular 1200 milya (1097 m) gacha miltillovchi osongina ko'rishlari mumkin edi. Va nihoyat, ular 200 metrga taymer va peyntbol quroliga ulangan holda o'q otish miltig'ini o'rnatdilar. ; bir kishi tirgakni tortib olganida, 231 milodiydan so'ng to'g'ridan-to'g'ri boshqasining ko'kragiga peyntbol otilib chiqardi. Miltiqni 500 yd (457 m) (600 milodiy kechikish) ga ko'chirguncha va Gollivud blankalari yuklanmaguncha, ikkalasi ham o'q otishdan qochib qutula olmadi. Odam va Jeymi afsonani buzishgan deb e'lon qilishdi, chunki snayper nishon tumshug'i miltillashini (shu jumladan, chaqnashni bostiruvchi) ko'rmaslik uchun ehtiyot choralarini ko'radi.

Oxirgi sinov uchun terminal tezligi, soatiga taxminan 120 milya, Tory vertolyotdan 183 metr balandlikda ikkita cho'chqa tana go'shtini uloqtirdi, shundan so'ng ular jarohatlarni aniqlash uchun rentgen nurlaridan o'tkazildi. Yo'lning pasayishi natijasida 17 ta sinish, tos suyagi singan va boshi kesilgan, suv tomchisida esa etti sinish va bo'yin singan. Hech qanday suvga tushish bir xil balandlikdan yulka ustiga tushish kabi zarba kuchi yoki jarohati hosil qilmagani uchun, jamoa afsonani buzilgan deb e'lon qildi.

For full-scale testing, the team outfitted a karta to match the mass and top swimming speed of a typical yelkan baliqlari and hooked their line to it from a star-drag reel. Kari drove it at 68 mph, while Tory applied drag and Grant measured the temperature. The first two runs gave a peak of 530 °F and smoked without any fire, even after Tory used larger amounts of flammable lubricant on the second run.

Declaring the myth busted, the team brought in a professional motorcycle racer and his sidecar rig to achieve higher speeds. Tory changed the lubricant out for even more flammable engine starting fluid. Runs at 140 and 180 mph gave temperatures over 700 °F, with the second of these causing the line to melt without burning. Finally, Tory set the reel on fire by exposing it to an open flame.

They set up six mirrors to bounce light back and forth down the length of the shop, using a spotlight as the source. Polished metal mirrors gave 1.13 lux, but caused the beam to spread out after only a few reflections. When modern glass mirrors were used instead, the light level registered at 0.49 lux and the beam stayed focused longer. Adam and Jamie realized that the light needed to scatter in order to illuminate the room.

Da Treasure Island in San Francisco Bay, they set up a hangar area as a full-scale tomb and brought in six glass mirrors and a 7,000-watt spotlight. After adjusting the mirrors, they measured a light level of 2.3 lux and could easily see their way around. Once the sky cleared, they reflected sunlight into the tomb and found a peak of 2.5 lux until the sun's position shifted, throwing off the mirrors’ alignment. Finally, Jamie stood in the light beam, which scattered in the air when it hit his white shirt and gave 8.6 lux. The need to keep adjusting the mirrors, and the unlikely prospect of finding several of them ready to use after thousands of years underground, led them to declare the myth "plausible but ridiculous."

Next, Grant and Tory tried to sandwich Kari's car from either side and managed to stop her, though they began to spin out somewhat. The two men then built car-stoppers: side paddles to attach to two rescue cars’ front bumpers and maneuver to block in the runaway (Grant), and a hood-mounted spear to hook the rescue and runaway cars together so the rescuer can slow them both down from behind (Tory). Both rigs worked without endangering either Kari or her rescuer(s).

For full-scale tests, they used a mast fitted with sensors at depths of 6 in (15 cm) and 2.5, 15 and 25 ft (0.8, 4.6 and 7.6 m), with a fifth at the surface. The first two depths were intended to represent the depth at which a swimmer's torso would be submerged if he were floating or treading water. A 10 lb (5 kg) charge of TNT was set off at a depth of 15 ft (5 m) and a set distance from the sensors (30, 70 or 150 ft (9, 21 or 46 m)).

Using a pressure threshold of 87 psi (corresponding to a 50% mortality rate from the shock wave), Adam and Jamie found that a floating person would survive at 30 ft (9 m), while greater depths led to pressures likely to cause death. At longer distances, the readings fell below 87 psi. Based on the 30-foot results, they declared the myth confirmed. Jamie attributed these results to the fact that much of the energy from the underwater pressure wave dissipated into transverse waves when it reached the surface.

Using an armor sample (¹⁄₂ in (13 mm) paper vs. ¹⁄₃₂ in (1 mm) steel) placed over a block of clay, they tested resistance to blunt force, swords, and arrows. The paper did as well as steel in the sword and arrow tests, failing only the blunt-force test, so the team built a full suit of paper armor to match against a period-accurate steel counterpart.

Each team member ran one of three timed courses in both armor types to evaluate speed, endurance, and agility; paper outperformed steel in all three. Finally, they attacked the suits with arrows, swords, and two firearms — an 18th-century toshbo'ron pistol and a 19th-century .45 revolver. The armor types resisted every attack except the .45, leading the team to classify the myth as plausible. They pointed out, though, that the paper armor could quickly begin to disintegrate if it got wet or took repeated blows (which happened during the full-scale tests).

At this point, Adam and Jamie decided to try to improve a motorcycle's aerodynamic performance so that it would use less fuel and give lower emissions. They built a teardrop-shaped shell to cover the entire vehicle, with a tubular steel frame and heat-shrink plastic sheeting. Jamie then drove simulated city and highway courses at Alameda dengiz havo stantsiyasi on a modern motorcycle, with the shell on and off. The shell gave the best fuel efficiency and lowest CO2 emissions, but did not perform better than the cars on the other three pollutants. They classified the myth as busted, and Jamie attributed this result to the fact that car pollution technology has advanced faster than that for motorcycles.

With help from Institute personnel, they built a rig to launch an RPG directly toward a remote-controlled gun of the same caliber as that used in the film (a Smit & Wesson Model 460 revolver). After a failed first test, they were able to hit the RPG with a bullet and see the former explode in midair. Separate shots of the two weapons on an 80-foot test range, the same distance as the film scene, led them to calculate that the bullet and RPG would collide 16 feet in front of the RPG shooter. However, the particular rounds used for these tests had jumboq systems that would not arm until they had flown roughly 60 feet.

The team set up two dummies 80 feet apart, outfitted with pork-belly abdomens and foil burst gauges to evaluate injuries. Assuming that the film RPG might have had a defective fuze, the team set up a target 16 feet in front of the RPG dummy, backed the launcher up to ensure a detonation, and fired. Both dummies survived without injury, though molten metal flew through the air just to each side of the handgun dummy and his survival was chalked up to sheer dumb luck. The need for a bad fuze, the forward direction of the explosion, and the fact that the intended target survived only through luck led the team to call the myth busted.

To simulate miniature wrecking balls, Adam and Jamie filled five 6 in (152 mm) hollow steel balls with plaster that had properties similar to concrete. This version gave only 63% efficiency, but Jamie suggested putting a steel plate through the center of each ball to reduce energy transfer into the concrete. They then built five 2,000 lb (907 kg) balls by cutting hollow naval buoys in half, sandwiching a steel plate in each, and filling the space with armatura va beton. When the rig was assembled at Mare Island dengiz kemasozligi and hung from an I-beam frame, it gave very poor efficiency and quickly stopped swinging, even after each ball was hung from two cables rather than one as shown in the video. Adam and Jamie declared the myth busted, noting the increased potential for energy losses at large scales, and later learned that the original video had indeed, been faked confirming their initial thoughts.

With these two still in the car, birds were brought in and allowed to perch on the hood. Two pigeons (1 lb (454 g) each), two hawks (2.5 lb (1.1 kg) each), and an burgut boyqush (7 lb (3 kg)) were tried separately; none were able to do more than wobble the car slightly. Grant commented that although a weight near the front bumper gave a large amount of kaldıraç, the car itself had enough weight to counteract the effect.

The team located a model helicopter and modified it to weigh 20 lb (9.1 kg), the same as a Kaliforniya kondori (the largest flying bird in North America). When this too failed to tip the car, the team classified the myth as busted and set out to find out how much weight it would take. The car only tipped after Kari put 80 raw, 1.5 lb (0.7 kg) game hens onto the hood and Tory added a raw, 20 lb (9 kg) remote-controlled turkey for a total of 140 lb (64 kg).

Ushbu afsona qayta ko'rib chiqildi Bird Balance Limo 2012 yilda.

For a real-world situation, they then decided to investigate the ability of a person to navigate a straight course if lost in the woods. With no landmarks or destination in view, they tried to follow separate headings for 30 minutes and succeeded by using the sun's position to stay on track. However, with buckets on their heads to simulate reduced visibility at night or in a snowstorm, Adam did poorly while Jamie stayed on track by carefully pacing around obstacles, drawing on his cho'lda omon qolish tajriba. Finally, they attached themselves to opposite ends of a long ladder with hip belts, thinking that each could feel the other's veering and correct it, but failed the open-field walking test again.

Declaring the myth busted at this point, the team traveled to the New Mexico Institute of Mining and Technology to use the on-site rocket sled apparatus. After setting off a 100 lb (45 kg) load of explosive to determine the appearance of the actual blast, they set a target car on the track, with the same size load, and fitted a pickup truck's front end onto the sled. Enough rocket motors were attached to accelerate the sled to a top speed of 300 mph (483 km/h), but the impact only disintegrated the target car without triggering a detonation. A cloud of undetonated Tannerite was visibly sprayed in all directions by the force of the impact.

The tests suggest that Tannerite is difficult to detonate unintentionally, the myth being that it was detonated unintentionally. Other binary explosives, however, may not necessarily be as safe.

For sensitivity tests, they rigged a full, 7 lb (3.2 kg) cooking pot to fall on a piece of burning C-4 from 3 ft (91 cm), then set up a robotic leg in a combat boot to stomp on it. Neither of these trials produced an explosion, so they dropped a 90 lb (41 kg) anvil on the material, without success. Shooting at the C-4 with different .308 rifle cartridges – standard, iz qoldiruvchi, olovli – failed to trigger an explosion as well. Finally, Adam and Jamie set up a termit charge to drip molten material at 4,500 °F (2,482 °C) onto the C-4, thinking that extreme heat might make it sensitive enough to detonate. This test failed as well, and Jamie noted that C-4 was formulated to be stable unless set off by a portlash qopqog'i. He and Adam judged the first half of the myth as confirmed, but the second half as busted. Jamie added that stomping on burning C-4 is still a bad idea, but more because it burns at a very high temperature and tends to stick to the bottom of shoes, rather than any risk of it exploding.

After a few refinements to his design, he was able to take the head off and have it retained within the device. Kari and Grant set up a combat situation, involving one moving enemy dummy and a second that could pop up from behind a screen. Tory hit the pop-up enemy with a glancing blow and knocked it down, but could not land his device on the moving one. Based on these results, the team decided that the flying guillotine was plausible as an assassination weapon, but not in combat.

They next built a 40 ft (12 m) sewer in a trench using concrete culvert sections, installed three manholes, and placed rolls of chain-link fencing in it to simulate debris. After burying it under 3 ft (91 cm) of dirt, they pumped in the methane and set it off. The resulting explosion threw the covers 150 ft (46 m) skyward and slightly shifted the dirt over the sewer. High-speed footage showed fire coming from only one manhole, indicating that a deflagratsiya had taken place rather than a portlash. Judging the myth confirmed at this point, Adam and Jamie noted that a detonation might have sent the covers even higher.

Fatal Flashlight

Bomba poligonida ular ishga tushirish va portlash o'rtasidagi kechikishni o'lchash uchun C-4 zaryadini va yuqori tezlikda ishlaydigan kamerani o'rnatdilar. Atrof-muhit haroratidagi bomba bilan boshqarishni boshqarish 3,3 millisekundaga kechiktirdi, LN2 ni to'g'ridan-to'g'ri zaryadga quyish uni 15 millisekundagacha oshirdi. LN2 zaryadga ham, qo'zg'atuvchiga ishlaydigan batareyaga ham to'kilganida, 15 minut o'tgach, butun burg'ilash moslamasi atrof-muhit haroratiga qizib ketguncha bomba umuman portlamaydi. Adam va Jeymi bu texnikaning aslida ekanligini izohladilar Ko'proq filmdagi kabi haqiqiy hayotda samarali; belgilar shunchaki o'rnidan turishi va hammomdan chiqib ketishi mumkin edi.

Mifning uchinchi qismini sinab ko'rish uchun ular filmda ko'rinib turganidek og'ir cho'yan vannali hammom majmuasini qurishdi, Busterni vannaga adyolga qo'yishdi va vannaga datchiklar o'rnatib, ichi va tashqarisidagi bosimni o'lchashdi. Tualet ostiga 1 kg C-4 zaryad o'rnatilganida, vannadan tashqari barcha to'plam yo'q qilindi. Vannadan tashqaridagi eng yuqori bosim o'ldiruvchi 180 psi (1,2 MPa), ichki datchik esa 8 psi (55 kPa) ni qayd etdi, ya'ni odam omon qoladi, ammo eshitish qobiliyatiga zarar etkazish ehtimoli bor. Adam va Jeymi afsonani tasdiqladilar.

Tracy Munitsipal aeroportida Build Team 9 kishilik akrobatik parvozlar klubi bilan uchish formasiyalarini sinab ko'rish uchun uchrashdi: V, qanot uchi qanot uchiga, bitta fayl va shakllanishsiz boshqarish. Qattiq V nazorat bilan taqqoslaganda yonilg'i sarfini 3-5 foizga kamaytirdi, qolgan ikkita qatlam esa hech qanday pasayish bermadi yoki yonilg'i sarfini oshirdi. Jamoa bu vaqtda afsonani tasdiqlaganini e'lon qildi, ammo yaqin shakllanish uchuvchilar uchun xavf tug'dirishi mumkinligini ta'kidladi. Ikkinchi marshrut, samolyotlar bir-biridan uzoqroq masofada joylashgan bo'lib, etakchi samolyotlarning girdobida qolish qiyinligi sababli faqat Toriga yoqilg'ini tejashga imkon berdi. Shunga qaramay, jamoaning ta'kidlashicha, yoqilg'ining ozgina tejalishi ham katta miqyosda katta moliyaviy afzalliklarga olib kelishi mumkin.
