Bite-Size Physics

You need:

Penny

Glass

Good set of lungs

This is a good one but it takes some work to pull it off.

1. Balance a penny flat on the top of an upright glass.

2. Now try to blow the coin in such a way that it blows over the glass. It’s impossible unless you know the trick.

3. Here’s the trick, blow over the penny. If you can blow straight over the

penny, the Bernoulli principle will lift the penny and send it shooting over the

other side of the glass. This is quite tough but once you get the hang over it

it’s a lot of fun to show other folks.
