Quarter Shrinker

Science is so cool! Anyone who thinks differently hasn't seen this video. They took a standard US quarter and shrunk it to the size of a dime. You need to see this.

At it's core what they are doing is really simple. If you have ever played with magnets, you know that when you have two like poles they repel each other. If you put electricity through a wire you can create a magnetic field. What they did was turn the coil that surround the quarter, and the quarter itself into really strong magnets. Since the magnetic fields were repelling each other push on the quarter in all directions, shrinking it.

This is cool science in action!
