PROTOTYPE #3

We used Benchmark #13 to develop this prototype. The swing is pulled by a cord and released to launch the ball. 

By testing this prototype, we realised it doesn't work, the ball simply doesn't come out of the thrower. 

CONCLUSION

Expected positive feedback:

/

Unexpected positive feedback: 

/

Expected negative feedback:

Not enough power to launch very far.

Unexpected negative feedback:

The ball doesn't even come out of the thrower.

Makeability score: 4 (quite easy to make)
