Make a Foam Rocket

This space rocket is easy to make and doesn't require fire or explosives to launch, making it an ideal classroom project.

Steps

Cut the foam pipe into one foot (0.3 meter) lengths.
Attach a cable tie to the rubber band (elastic band). Do not tighten all the way.
Place the rubber band/cable tie into the foam pipe, leaving an end of the rubber band exposed. The cable tie should be inside the pipe.
Attach the remaining cable tie securely to the end of the pipe so that the rubber band cannot be pulled through.
Cut off the excess cable. Be careful of sharp edges!
Cut fins from the foam tray. Experiment with different shapes, sizes, and number of fins.
Glue the fins to the foam pipe. If you have a hot glue gun, use it. Otherwise, use glue suitable for fabric.
Launch the rocket. Place the rubber band (elastic band) over your finger and pull back on the bottom of the rocket. Move your arm forward in a throwing motion as you release the rocket.
