The flying mouse is very easy to make and you can crank them out quickly for a large group. They’re also interactive–the kids can send them flying through the air which is just plain awesome. Follow the directions in this Youtube video. The first part is about making a sword, so just skip forward to about the middle to see the mouse directions.

A magician friend of mine recently showed me how to do this, except he calls it the jumping mouse. I did it at a few kids parties, and they went crazy for it! It was a huge success!! The beauty of it, is it is such a quick and easy design to do.
