Toss the ball in the air and watch the colours magically flip! These fascinating balls transform back and forth between two colours. Amazing!!! Chemistry teachers - for a great Activation Energy Demo, see the Pair of Switch Pitch Balls listed below.
Pair of Switch Pitch Balls: Gently toss one in the air without spin and notice no change. Repeat with increasing energy until a change occurs. A beautiful lesson in activation energy! Point out the activated complex. Show the difference between translational and rotational energy. Use to demonstrate the activation energy needed for a reaction when two particles collide.
