Party Popper Prototype

My group and I tested different party poppers.

First we tested different rubber bands to pick. We tested the thick rubber, and then we tested the medium rubber band, last we tested the small rubber band.  My group and I thought the medium rubber band was the best because it hit the cup loud and hard.

Next we choose something for our weight. My group tried out a pen for the weight, the pen shot the filling out great. So we chose the pen.

Lastly, we put everything together and tried it out. It was loud and great. The filling went out of the cup. 

I learned a lot about making party poppers.
