1.2 Bouncing balls

You will need:

- A piece of kitchen foil

- A piece of thread

- A wine glass

- A spoon

 

Instructions:

1.- Screw up the kitchen foil into a ball and tie a piece of thread around the foil.

2.- Put a wine glass on the table. Hold the thread so that the foil ball just touches the glass.

3.- Gently tap the other side of the glass with a spoon. What happens to the foil? (The ball should jump away from the glass. As you tap the glass, it vibrates and makes a noise. The vibrations make the ball move)
