Conservation of Angular Momentum: Squeezatron

Instructions / Notes:

• Two heavy masses are attached to a framework that spins freely.
• When the central string is pulled upward, the masses are drawn toward the center post and spin faster.
• The faster the framework spins initially, the more difficult it will be to pull the string.
