What you do (Air pushes back): 1. Draw a T shape on a paper strip and cut it out with safety scissors (an adult helps). 2. Cut the top down the middle and fold the two blades opposite ways. 3. Fold up the bottom and clip a paper clip on it. 4. Drop it from your raised hand and time how long it takes to land.
