Rapid Rubber Band Launcher Force And Motion Science Experiment
In this fun and easy science experiment, we’re going to explore and investigate force and motion by building a rapid rubber band launcher.
Note: This project requires adult supervision and assistance. Please use caution and the proper safety equipment when using tools and hot glue guns.
- 12 inch section of one inch diameter PVC pipe
- Eight to ten clothespins
- Hot glue gun
- Glue sticks
- Rubber bands
- Carefully cut a groove into on end of the piece of PVC pipe about an eighth of an inch deep. Now cut an identical groove an eighth of an inch from your first groove. This will create a post on the end of your rubber band gun barrel.
- Now put a rubber band around the post and stretch it along the length of your PVC pipe. Mark the spot where the rubber band it pulled taunt.
- Next, using the hot glue gun, glue a clothespin at the spot you just marked.
- Work your way around the PVC pipe gluing clothespins side by side until no more will fit.
- Count the amount of clothespins you were able to fit on your pipe and now return to the barrel of your rubber band launcher.
- Cut more sets of notches into your barrel that match the number of clothespins on your rubber band launcher.
- Once the hot glue has set and dried, load your rubber band launcher and enjoy!

How it Works:
Rubber bands are loaded with potential energy. Once the stretched rubber band is released, the potential energy (stored) coverts to kinetic energy (motion) that you are able to observe.
Make This A Science Project:
Try different sized rubber bands. Try using rubber bands that have been placed in the freezer. Use different lengths of PVC pipe.
