Molly and Will are attending "AeroSpace Camp" at the Tulsa Air and Space Museum. They are learning a lot and having a great time. Today they studied Boyle's Law of Gases and made a Cartesian Diver as a demonstration.
You may notice that Willy is sporting a new haircut courtesy of Grandpa Bill. I buzzed him with dog clippers.
A weighted eyedropper is placed inside a plastic bottle of water and the bottle is tightly capped. At normal pressure the eyedropper floats at the surface of the water.
When pressure is applied to the bottle the air inside the eyedropper becomes more dense and the dropper slowly sinks to the bottom of the bottle. They were very excited to show us the marvel. If my explanation was not clear you can see a better explanation HERE.
They are doing all sorts of things at the camp including flying in a real airplane simulator. Yesterday they made a simple rocket using an Alka-Seltzer tablet. They put a little water into an empty 35mm film canister, dropped an Alka-Seltzer tablet in it, quickly put the lid on the canister and turned it upside down. The expanding gas blew the canister up over their heads. They said it was really cool. If you are interested in knowing more about the Museum and Planetarium look HERE.

Bonjour.
Je m'aperçois que je vous ai lu tout à l'heure (en Français) mais que je n'ai pas commenté.
Sorry.j'ai un peu la tête ailleurs.
Profitez bien des petits qui ont l'air de faire un stage intéressant.
Bisous à tous les 4 et caresses à Smokey.
It's important to start when young and what a great way to learn about Boyle's. Wish it was that fun to learn it when I was young too.
