Code Number: 1Q60.51

Demo Title: Spinning Loop - String Shooter

Condition: Excellent

Principle: Air Drag Force - Stable Loop Shape

Area of Study: Mechanics

Equipment:

String Shooter

Procedure:

The string shooter and loop are pretty much ready to go out of the box. Make sure that the loop doesn't get tangled when you first turn the unit on. This can be done by using your finger to hold the side of the loop going into the spinning wheels when you first turn the unit on until loop has formed a stable shape.
