Hanging Inertia Ball

This experiment uses a heavy steel ball hanging from a support structure by a thin cotton string. If you pull on the bottom string quickly the bottom string breaks due to the ball's inertia, if you pull on the bottom string slowly and allow the ball time to have a chance to move then the upper support string breaks.
