Will a sinking ship suck you down as it goes under? Are goldfish bored or just plain stupid? Will throwing a lit firecracker down the neck of a trombone make your music sweeter?

In this episode the Mythbusters test:
1) If a sinking ship can suck you down and kill you if you are next to it.
2) If goldfish can remember things.
3) They see what happens when you drop explosive material inside a trombone.
