Instructions

1. Turn the tap on slowly, stop when you just get a complete stream of water to flow, i.e. small flow.

2. Run the comb through your hair at least 10 times. Dry hair makes the experiment work better.

3. Move the comb toward the stream of water. What happens to the stream?

4. Run the comb through your hair again and repeat the experiment. Does the stream change again?

You will need:

- 1 nylon comb

- A water tap
