This is simple, if you know of a myth that could possibly get busted, post it here and suggest some kind of test. If some other Fooster can test it, please do and post the results here. I'll start:
Antigravity fields & Magnets
The myth says that you can create a simple contraption that will create some kind of antigravity field, canceling some of the earth's gravity forces on it. To make the contraption:
1) Get 2 big speaker magnets.
2) Get a screw and some washers and nuts.
3) Use the screw, washers and nuts to force the 2 magnets together, with the repelling poles facing each other (the 2 south or the 2 north).
Now go to a high place and let it fall. Science says that every object falls at the same rate regardless of weight, with an acceleration of 9.8ms^2. The myth says that this antigravity contraption will fall at a measurable slower rate.
Anybody wanna test this? Any other myth you want some other Fooster to test?
