Sarah is participating in Starbase. A local program to promote math and science in schools. She has had so much fun. She is launching a rocket that she built today. This video was for extra credit. She is demonstrating Bernoulli's Principle.

Hey....I saw something like that on a show last night...one of the late shows, but I don't know which one. They used a leaf blower and attached a paint roller to the end of it. There were 3 rolls of crepe paper on the paint roller and when they turned the leaf blower on, the crepe paper went everywhere!!
When we first tried to demonstrate the principle, we had a full roll of toilet paper and it didn't work. I asked Sarah what they had used at school and she said a leaf blower. No wonder our first try was not a success! We got a 1/2 used roll of toilet paper and the blow dryer worked fine. Too funny that you saw it on TV.
