Discussion questions

Talk about it

Air squeezed into the tank presses on the water. Open the valve and the pressure shoves the water out in a powerful stream.

  1. How does a Super Soaker use air to push water?
  2. Why does more pressure make the water shoot farther and harder?
  3. What everyday tools also use pressure to move water or air?

Quick work-a-long
