Air Experiment 2

 Using air to have a race.  First take a piece of paper and fold up 1 inch of the edge.  Use a piece of cardboard, or thick cardstock paper, and wave it to make it push the air around you, in turn pushing the paper on the floor.  We had a race.  The line difference from the carpet to the wood was the line, but you could make a line with string or something.  Then RACE!  Monkey won the first race, and then Bear figured out how to really get it to go and he won the second race.  We kept it a tie. :)

 Air!  You can't see it, but you can see the evidences of it! :)
 Another simple yet fun experiment for the kids.
