Bernoulli's Law

For my Bernoulli's Law project, I chose to do something with a penny that my dad taught me. This is what you do:
1. find a penny
2. once you have your penny, place it on a flat space
3. blow as hard as you can on the top of one of the sides
What is supposed to happen:
Your penny is supposed to jump into the air, and flip over. It is really hard to make it actually flip, but making it jump is much easier.
Why this happens:
Well, when you blow hard on the penny, your breath is a fast moving fluid that blows over the top of your penny, causing it to jump into the air and hopefully flipping over. I'm not exactly sure where the low pressure point is, but I belive it's on the underside of the penny, because there is no fast moving fluid on that end of the penny, and nothing is really happening down there.
Why this works:
This works, because the force of your breath forces the penny up, and it then flips over, and you can see the other side of your penny. It is really hard to do, and most of the time, I cannot do it.
