影片内容介绍
剧情简介
| Myth statement | Status | Notes |
|---|---|---|
| Greenhouse gases increase the amount of heat absorbed by air. | Confirmed | Airtight containers with carbon dioxide or methane added got one degree Celsius (2 °F) hotter than regular when heated by a hot lamp. |
| Electric cars are more sluggish than gasoline-powered cars. | Busted | They first had Jamie drive Brandon (a Young Scientist Challenge winner) in both a gas and electric consumer grade car, and blindfolded Brandon and covered Jamie’s ears to see if they could tell the difference. Brandon couldn’t tell, but being an experienced driver, Jamie was able to immediately tell based on the electric car’s acceleration. Then Adam, Jamie, and Brandon built an electric go-kart using lithium iron phosphate batteries and tested it against a gas go-kart. Despite weighing twice as much as the gas go-kart, the electric go-kart performed about the same. Then they went to a professional track and watched the KillaCycle, an electric drag motorcycle race against a stock gas motorcycle. The gas motorcycle won by a slight margin. Then they had the X1 electric sports car race against an F430 Ferrari, and while the Ferrari’s top speed was faster, the electric car accelerated faster and beat it in a drag race. Finally, they had the electric car race against a FJR50 Formula 3 race car. While the Formula 3 car easily beat the electric car, the electric car is considered a “street car,” not a race car, and it did well enough that they proclaimed electric cars to be anything but slow. |
| Cows hurt the environment. | Confirmed | Cows emit methane—though not mostly from flatulence, but from belching — and their feces emit even more methane once they begin rotting. Since there are so many cows, the methane contributes significantly to global warming. |
| Cow manure can be used to help the environment. | Confirmed | Cow manure can be used to power things. The Young Scientists helped collect cow manure and extracted methane gas from it. Grant hooked up the methane gas and used it to power a hand lawnmower. They then saw that the farm where they had collected cow manure from received 90% of its electricity from its own manure-powered generator. |
