Editing Uncertainty Principle (section)

== Demonstration ==

;Preparation: Prior to starting this demonstration, ask the contact to show you where the controls for the lights are in the location. If you have a volunteer with you, assign them control of the lights for this demonstration.

# Set out the ring stand and hang the ping-pong ball from the clamp. Explain to the audience that we can track the location and movement of the ball quite easily.
# Explain that tracking objects on the atomic scale is much harder. Ask for the lights to be turned off, and explain that you can use your "Quantum Hairdryer" to try and find the atomic particle.
# Turn on the light and the hairdryer, and try to find the particle. Every time you find the particle with the light, the air blows it away! Chase the ball with the blower for a few seconds before turning it off, and having the lights come back on.
