影片内容介绍
剧情简介
| Myth statement | Status | Notes |
|---|---|---|
| It is easy for a person to recognize the back of his/her own hand. | Confirmed | Adam and Jamie took pictures of the backs of 100 people’s hands, 50 of each gender. Each of 12 more volunteers had a hand picture taken and mixed with 9 others of the same gender, race, and hand size/shape, and then had to try to identify it within 60 seconds. Volunteers wore gloves during the test to prevent cheating. Eleven of the 12 chose correctly, prompting Adam and Jamie to investigate the ease of identifying other body parts—namely, palms and teeth. Using the same methodology, 7 of 12 were correct on the palm test, 10 of 12 on the teeth. |
| Monk Magic: It is possible to throw a needle hard enough to penetrate a pane of glass without shattering it. Based on a viral video of a Shaolin monk performing this feat. | Busted | The Build Team started by throwing needles at panes of typical window glass, with thickness 0.125 in (3.2 mm). Their top throwing speed was 47 mph (76 km/h), but all of their needles only bounced off. San Francisco Giants pitcher Matt Cain tried next, achieving speeds up to 113 mph (182 km/h), but only bent several needles and eventually struck a large chip out of the pane. When the team switched to 0.0625 in (1.6 mm) glass, Matt was still unable to penetrate it but did manage to shatter one needle; with 0.03125 in (0.8 mm) antique glass, he smashed it on his first throw. The team declared the myth busted for human throwers at this point, but Tory modified an air rifle to fire the needles at high speed. Using 0.125 in (3.2 mm) glass, they got no result at 140 mph (225 km/h), chipped the glass at 160 mph (257 km/h), and finally punched a clean hole at 180 mph (290 km/h). |
| Underwater Bike Ride: It is impossible to ride a bicycle underwater. | Busted | Adam and Jamie considered the effect of water resistance and underwater buoyancy forces on a rider’s stability and balance. In the shallow end of a swimming pool, Adam was able to pedal and stay upright with his upper body above the surface. However, when he tried again at the deep end, the buoyancy caused him to tip over backwards. He donned 50 lb (23 kg) of ballast and a scuba tank, but still lost traction and was unable to turn or ride uphill without tipping. Jamie then tried to ride the bicycle himself, with the same results. They worked separately on modifications to improve traction on the uphill run. Adam added 50 lb (23 kg) of weight to his bicycle’s frame and filled its tires with corn syrup to flatten them out, while Jamie mounted a 120 lb (54 kg) set of lead training wheels and attached another 20 lb (9 kg) weight in front. They laid out a race course at the bottom of the pool, but neither man was able to ride his modified bicycle on its uphill portion without using his feet to push ahead. They classified the myth as busted, since they were able to ride on flat and downhill runs. |
| The “potty dance” can help a person with a full bladder stave off the need to urinate. | Plausible | For a control run, each Build Team member came to work with a completely empty bladder, drank 2 liters of water, then measured the time until he/she could no longer resist the urge to urinate. Tory lasted 1 hr 58 min; Grant, 1 hr 58 min; Kari, 2 hr 39 min. They debated the effectiveness of the “potty dance”: distracting attention from the full bladder versus putting more pressure on it. The second day, they repeated the trial but allowed themselves to do the dance. This time, Tory lasted 1:30, Grant 1:52, Kari 2:46. On the third day, they tried various methods to relax as much as possible. Tory lasted 2:05, Grant 2:46, Kari 2:43. The team judged the myth plausible, but noted that results of different methods can vary widely from person to person. |
