Editing Angular Momentum Chair (section)

== Demonstration ==

# Choose a volunteer from the audience to come and sit on the stool, with their feet on the bar. Give them the hand weights, and instruct them to hold the weights out sideways. Then, after you start spinning them, they are to pull the weights in when you say "GO". Perform the demonstration.
# Now have them do it again, but this time have them start with the weights held to their chest, and on "GO" they extend their arms outward. Thank them for volunteering and have them return to their seat. Explain the first part of the demonstration at this time.
# Choose a new volunteer, someone who can hold the wheel up and away from themselves without the wheel hitting them. Have them sit on the stool, with their feet on the bar, and give them the wheel. Have them try to turn it on its side, to see if they can hold it Point out that, right now, nothing happens when they do that.
# Take the wheel back, and get it spinning quickly. Hand it back to the volunteer and have them turn it on its side again. They will start to spin!
# Thank the volunteer, and have them return to their seat. Explain the demonstration.
