My invention is a balloon popper. It is used to pop
balloons.
-
I used four different materials for my invention.
They are "k"nex," a string, fools gold and a silver needle.
-
The design was a catapult with a string attached to the long
end. The other end had a gear with a string attached on it.
-
There is a silver needle.

The balloon popper makes you not have to hurt yourself went
you sit on it .
