Forces & motion
A falling ball in one tube produces an air pulse that launches a smaller ball in a second tube.
THE PRODUCT IN MOTION
Visitors lift the large ball using a rope and then release it. The rapid air compression produces the visible launch; the installation is not presented as an isothermal gas-law measurement.
Video & text guideTHE ACTIVITY & MECHANISM
Lift the large ball with the rope, then release it using the exhibit sequence. Watch the smaller ball rise in the connected tube. The falling ball rapidly compresses the air, which transfers energy to the smaller ball. Follow both balls to connect the initial movement with the later launch.
Lift the large ball with the rope according to the station instructions.
Release it using the instructed sequence and keep clear of moving parts.
Follow the smaller ball as it rises in the other tube.
