Purpose: Demonstrate inertia of rest.
Description: This commercial toy consists of a stack of blocks with each layer placed 90 degrees to the prior one. The object of the game is to remove blocks from the lower part of the tower without knocking the whole structure over. Trying to do this gently is usually doomed to failure: a quick flick of the finger is the most effective method.
