How to Build a Ball Bearing Gun
Hobby weapons that simulate real guns and rifles typically fire small ball bearings, or BBs. You can build your own gun to shoot a ball bearing at a target. You will need a few common household supplies, along with a standard-size party balloon that can be purchased at a party store or drugstore. Your ball bearing gun will not need gunpowder or a spring and will be able to fire as quickly as you can reload.

Tips & Warnings
You can use a paper towel tube and a larger balloon to provide more shooting power to the ball bearing.
Because of the wide barrel of the toilet paper tube and the tiny size of the BB, don't expect to be an accurate shooter.
Adult supervision may be required, since a cutting edge is used.
Wear protective eyewear when firing your ball bearing gun.
Never aim a homemade weapon or any weapon at a person or domestic animal.
