In this instructable we create an elastic (rubber band) powered car from scrap material. The car uses a few important physics principles to travel and also teaches skill to use the all important GLUE GUN! There is a lot of variations of elastic powered "cars" and this variation adds a little elegance to the bunch. This one also does not get your fingers caught in a mouse (or rat) trap. I have built three versions to date, all using different chasis and this one, although not the fastest, is the one that travels the longest distance.
Step 1: Materials and tools
Look at the pic and improvise.. This is a very flexible piece of work that can be modified as you go along. Ignore the soldering iron in the tool picture, it was taken from another instructable.
Plastic drinking straws
Small (25ml) plastic containers
Old/used optical media for wheels
Other plastic caps for wheels (Size does not matter!)
