Party Popper Prototype

My company, The Three Inventors, made a prototype of a party popper. 

First we chose the material for the prototype. We tested the parts of the prototype of which part was the best that we could use.

Second we attach the parts together into a full party popper to see how it looks. 

Last we tested the prototype to see if we have any change for the party popper.  

I learned lots about making a prototype of a party popper. I think that we should make a different party popper to make the filling explode more. We should have used the bigger rubber band but when we saw the measurement we changed the bigger rubber band into a smaller rubber band.
