Things You'll Need
Instructions
Assemble a collection of small toy sailboats, or make your own out of folded paper.
Fill the 'kiddie' pool with water or go to a public wading pool.
Line the boats up on one side and try to get them to the other side of the pool. The first boat to get across wins.
Try blowing on the boats to make them go.
See what happens when you splash water behind them to make them go.
Catch the wind and let nature move the boats.
Use different boats and different paper designs to see which goes the fastest.
