Picture of The Cardboard Air Force
When I was a kid my grandpa used to buy me these cheap styrofoam gliders as a way to try to develop a love of avionics in me. For some reason the gliders were more fun than paper airplanes but they would inevitably break the first or second time I played with them. Skip ahead 25 years. I was recently in a shop and saw some of these gliders. For a half a second I thought about buying one for my son. Then I remembered the durability issues and decided it would be more economical and practical to build my own glider.

This instructable will teach you how to build a simple glider. I will also attempt to show the results of a slightly more elaborate build for a biplane and a helicopter.

Step 1: The Materials

Picture of The Materials
I wanted this build to cost less than the cheap, easily breakable styrofoam  store-bought gliders. Since those cost about $1 that meant I was going to be using materials I already had at home.

1. Cardboard (I used a pizza box because my son is 2 and has small fingers. For performance the thinner cardboard of a cereal box would work better)
2. A writing utensil (Sharpie for me, please)
3. A cutting implement (I used scissors because my son wanted to help. An exacto knife would have given cleaner results)
4. A keyring ring (a paper clip would also work)

That was all that was necessary to make the basic glider. The slightly more advanced, and I use the term lightly, builds of the helicopters and the biplane also required the following.

5. Toothpicks
6. Hot Glue Gun
7. Hot Glue Sticks
