Try using pull string fireworks from party poppers, they work great.

ya my grandma has on i guess I'll ask her for a few bullets and make a triple shot!

What if the cannon spins around, and shoots some one lol. I don't think a triple shot will work.
Just anchor it down.
Let 'em taste the triple guns!
