The Coin Shooter

This is my coin shooter.  It shoots coins out of the blue balloon.  To make it, first you get a toilet paper roll that is empty.  Then get a balloon, any color, then cut it close to where it gets big.  Put duct tape around it then put a coin in the toilet paper roll and pull the balloon back then let go.  The coin will burst out!

This thing can shoot the coins very far and really high.  It acts kind of like a cannon.

I just found out that it shoot marshmallows better than coins.  Try those too!
