TF9.3 Surface Tension Demos

This consists of wire frames of objects that will form thin soap films. There is a regular loop and two cubic structures. Also there is a loop with a string in the middle. When one side of the loop is popped, the string stretches out and tried to close up the other side of the loop. Another has three wire sides and a fourth of elastic string. Pulling the string out requires force. When released, the string is pulled in by surface tension, decreasing the area.
