We rebuilt the catapult prototype since the wood had started to crack. We replaced the PVC "arms", making them longer so they supported the wood more. We tested it with one piston and it fired a little better than the last catapult prototype. We build our hammer design as well and tested it. We still need to build a good pedestal to place the ball on. A problem we noted was that the PVC pipe was bent a lot and looked close to the point of shattering.

Both our prototypes aren't shooting the ball very high.

Tomorrow we will be working on improving both our current prototypes (catapult and hammer).

We are on schedule testing our prototypes.
