Inspiration
This was another easy week inspired from my cub scouts days (thanks Mom).
Materials
Strip of tissue paper 18" x 2" (newspaper would work just as well)
Vitamin Bottle - any old 3" cylinder would do to create the needed separation
Notes
The setup for this is fast and easy, just cut and drape the strip of paper and make predictions. I start by blowing right at the side of the strips before asking for predictions of what will happen when we blow between or beside them. They guessed that the paper would move in the same direction that the wind was blowing predictably and were appropriately impressed when the paper moved in a perpendicular direction. We talked about air pressure and how faster moving air lowers the air pressure and can lead to lift with wings and such.
