Last night I spoke to Adam Savage, co-host of MythBusters. He's in Alaska, where current temperatures range between 0 to 30 degrees below zero. He just finished a test on "cabin fever" (he wouldn't say how long he lasted before murdering his cabin mates and running out into the frozen wilderness wearning nothing but longjohns and a sleeping cap) and is now working on another episode up in the 49th state.
But the real reason I talked to him was to find out about the next episode of MythBusters (airing this Wednesday). It tackles the famous "plane on a conveyor belt problem," that has pitted brother against brother and friend against friend for years.
To get to the bottom of the thought-problem, Adam and Jamie used a real plane, in this case a 400-lb ultralight, and a large conveyor belt. Did the plane take off? You'll have to wait until Wednesday to find out, but Adam said even the pilot guessed wrong.
