Mythbusters: Season 1, Episode 11

1 - 11:

Could prisoners really have escaped Alcatraz without a trace? Does a duck’s quack echo? Can a stud finder really prove if human beings have been guinea pigs in mind-control experiments. In this episode, the Adam and Jamie test: 1) If it's possible to escape from Alcatraz only with a homemade raft. 2) if quacks from ducks echo. 3) if the government implants chips in your body when you donate blood.
