MythBusters Show Summary

Did a Medieval Chinese astrologer make it into space by strapping rockets to his chair and setting them off? Just how hard IS it to find a needle in a haystack? Can you in fact go insane by having water drip on your forehead?

These are just a few of the myths, urban legends, and improbable sayings that the Mythbusters try to figure out. Comprised of special effects experts Adam Savage and Jamie Heineman - as well as their mottley crew of Mythbuilders, Mythterns, and resident 'crash test dummy' Buster - they don't just tell the myths, they put them to the test to see which ones are possible, and which ones are just plain bunk.
