Please feel free to follow along....

Watch how the warm air currents make the propeller spin... 



#2 - SOUND VIBRATIONS - Cover the top of a bowl very tightly with plastic wrap. Place several pieces of uncooked rice on top. Place the bowl near a speaker. Turn on some favorite music and watch the rice dance. Start out at low volume and gradually increase to see how the volume affects the movement...
