The assignment was to make an example of Bernoulli's law:
I made an air plane wing. I folded a piece of paper and put a straw through it. Then I taped it to the paper on both side. Thirdly I put a string through it and blew on top. The low pressure was on the flat bottom side, the high pressure was when I blew on top. the wing was supposed to go up which it did. So it worked great
