I'll be showing you how to make an extremely powerful homemade BB gun that can shoot through soda cans. Heres a video proving it can shoot through a soda can.

Step 1: The Materials

All you REALLY need for this project is:

A balloon
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.
