How To make a Indoor Boomerang

Intro : Indoor Boomerang

I teach a class called "Make and Throw a Boomerang in One Hour." Actually you make three boomerangs in this class:

1. A light weight indoor boomerang to learn the basics.
2. A heavy cardboard one that flies outdoors in a light wind
3. A boomerang made from heavy polystyrene foam that flies in light to moderate breezes.

All three use the same template. This instructable is for the indoor model.
