Now solve a Rubix Cube in 16 moves or less and then determine the force of gravity at any point (x) about a sphere of uniform density (thus proving Newton's Second Law).

Or start playing that snake game thing with the dots and they add onto it and you can't let it touch itself but it keeps getting longer and longer and longer..etc.

Now that's a real mind bender.
