Play-Dough Piano

Time: 30 Min.

Materials:
Play-dough
Aluminum foil
Tape

Process:
Tape down two strips of aluminum foil and attach an alligator clip to each strip. Complete the circuit between the two strips of aluminum foil using the play-dough. This will work best if your play-dough isn’t dried out. Try different shapes like balls and snakes. What happens when you squish the play-dough?

Sample Program:

Other Ideas:
Try different instruments. Hold an alligator clip in each hand. What is your resistance? Wet your fingers and try it again. Did it change? What happens if you touch one of the alligator clips to the same foil as the other one?
