In this episode of Mythbusters, four myths are explored. However, due to a lack of time, space, and the general attention span of the audience, I will be discussing just one myth today.
Over the course of the episode, four myths inspired by viral videos from the Internet were tested. The myths were, in order of appearance:
1. Can you lift a car using the pressure from fire hoses?
2. Do fainting goats actually faint?
3. Can you float a tinfoil boat without water?
4. Does an air-compressor fed sawdust cannon actually work? (see image above)
I will be discussing myth 3. As it turns out, you can quite easily float a boat with no water. During the experiment, Adam filled a fish tank with sulfur hexafluoride, a gas which is six times denser than air. Due to the increased density of the gas, the tinfoil boat could float quite easily on it. Adam also did a demonstration showing the difference between helium and sulfur hexafluoride. Check out the video.
this is really cool. i think you should watch episode 19 of season 2, the one about quicksand, it's pretty interesting
