 ===== Purpose ===== ===== Purpose =====
 +This device shoots out a loop of string in a continuous ellipse. With it you can show centripetal force and slow moving waves; if the loop is slightly disturbed, slow moving waves will travel along the string. ​

 ===== Setup ===== ===== Setup =====
 +Simply flick the switch. Make sure that the string isn't tangled up or caught on anything before you do.
 ===== Notes ===== ===== Notes =====
 +You may have to repair a string breakage. It isn't enough to just tie the broken ends of the string back together, since any knots in the string will get caught between the wheels. A needle and thread can be used to more cleanly splice the string back together. ​
 +The rubber on the wheels may also wear out. Currently it's made out of pieces of rubber balloon stretched over the wheels. ​
