What happens when you place a tennis ball directly above a basketball and then drop both of them at the same time? Jason Lindsey with Hooked on Science says a transfer of energy occurs that will create an out-of-control bouncing ball.
STEP 1: Hold the tennis ball directly above the basketball so that the balls are touching.
STEP 2: Drop both the balls at the same time and observe.
The energy from the bouncing basketball is transferred to the tennis ball. This causes the tennis ball to become energized and shoot into the air. Go to hookedonscience.org for more experiments that might get you “Hooked on Science.”
