The things that I used to make my catapult were Rubber band popsicle sticks, a big one and a small one.
To make my catapult I worked with Michael W. I worked with him because I had no one to work with and he doesn't have no one to work with so I decided to work with him.
The most challenging part was to attach the spoon onto the popsicle stick with the rubber band it was challenging to tie the spoon on the popsicle stick.
Overall I think that Me and Michael W work really well together so maybe we should work together next time.
