Here's another brain teaser for you (provided by my brother):

You are standing in a boat in a lake holding a rock. You throw the rock into the lake.

What happens to the level of water in the lake?

Again, assume all basic Physics 101 assumptions (no wind, no current, etc.).

Ding ding ding! And explained much better than when my brother explained it.
