| - | Show centripetal force and slow moving waves | + | This demonstration consists of a pair of DC motors mounted on a piece of MDF with wheels so that they can be used to propel a loop of string. A pair of batteries provides their power. |

| ===== 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. | ||
