A pair of scissors
and A toilet paper roll
Step 2: Cutting the balloon
Begin by cutting the balloon at the tip. Do this until it is fully removed.
Step 3: Wrap the balloon around the toilet roll
Take the balloon that you just cut and wrap it fully around the toilet paper roll. Then just re-arrange the lining to make it even.
Step 4: How to use it
Now your done. Too use it, drop the projectile into the barrel (the tip of the toilet paper roll) and pull the balloon back then release to shoot.
Step 5: Test shot
Testing this homemade bb gun, I decided to take a copper penny as the projectile and a soda can as the test subject.
Step 6: Results - Success
After shooting the soda can a good 3 times. The fourth time was a charm. It went right through the soda can like I expected. Hope you enjoy the BB gun. Please rate this instructable if you found it helpful.
