With a basketball?
I remember playing Physics with a basketball.
And a tennis ball.
Note: Do not play this game indoors.
It’s very simple. As a Physics demonstration, hold the basketball over and touching the tennis ball, then drop them together. The basketball will kinda squash the tennis ball and both will bounce poorly.
Now reverse the order. Place the tennis ball on top of the basketball, and drop them both together.
The basketball will hit the ground or pavement, and slightly collapse from its momentum. At the same time, the tennis ball will continue falling, and will slightly indent in the basketball.
And then the basketball transfers its compressed energy into the rebound of the tennis ball, and it could end up on the garage roof!
It’s astonishing! It’s also very surprising, if you haven’t seen it done before.
Have fun! And have someone young around to chase the tennis ball! It really goes flying!
