Prototype

 My company, arty rocky crafter  made a prototype of  party popper

First we selected parts of our prototype. For example we chose  paper cup because it can be cut easily. We selected  all of the parts of the prototype.

Next we made the prototype. It was so hard to tie the rubber band to the bolt because it kept untying. We made our prototype.

Last we tested our prototype the prototype was successful 

I learned a lot about how to make a prototype  I would like to have a big rubber band next time.
