Mythbusters teaches an essential principle of science: testing your hypothesis.
It doesn't matter that it might be "obvious to an 8 year old" that you can curve a bullet by swing your arms - obviousness is not a measure of correctness. Unless you have tested it you can't be sure.
Experimentation is king.
I enjoy watching mythbusters to see the outcome of their experiments, and see whether my own predictions are correct. I hope kids watch mythbusters take away the fact that the seemingly obvious can be wrong, and what appears to be fake is in fact real, that the only sure way to differentiate between plausible and busted is to try it
