For school projects - various model cars
We're planning on using these to make various model cars: balloon cars, mousetrap cars, rubberband-powered cars, etc. We bought these because bottlecaps aren't as cool looking or perfectly shaped and we don't drink enough bottled beverages to provide bottle caps for all the model cars each of our four kids are going to make!
