Boomerangs

This week's experiment comes from conversation I had with some talented science educators. We got into a discussion that ranged from gyroscopes to bicycles. The conversation led us into talking about boomerangs, so of course we had to make some paper ones to play with. The dynamics are a bit different with the paper ones, but they are still lots of fun.

Bernoulli in the Shower?

This experiment came as an accidental discovery while working on a different experiment idea. I was playing with ideas for showing how inertia helps remove water from your clothes in the spin cycle of the washing machine. In the process, I saw something interesting, and made a wrong guess about the cause. That led to even more interesting discoveries. There are times when it is more fun to be wrong, because it lets you learn new things.

An Easy Swing?

I have taught several classes on Amusement Park Physics, and I usually include several activities on the carnival type games. Those games often use science, making something look simple and easy, when it is actually difficult to do. This activity is based on a carnival game where you try to swing a weight on a string and knock over a bottle.

Newton's Third Law of Motion

This experiment comes from my hotel room. I was traveling do some consulting for a science museum, and was sitting at the desk, thinking of ideas for experiments. As I sat, I swiveled back and forth in the chair. As I swung back and forth, I decided that it would make an interesting experiment.

Making a Screamer

It has been a while since I did one of the noisy, annoying sound experiments which kids love and parents hate. Just keep in mind, that it is all in the interest of science.

You will need:

- a piece of paper about one inch wide and about 5 inches long.
- scissors
