PROTOTYPE #8

We kept the sandpapered wheels from the prototype before. But now, we worked on the aspect of the direction and the way the ball gets into the wheels by making a launch tube. The tube has to be exactly in the center.

CONCLUSION

Expected positive feedback:

It goes further and higher then all the prototypes before. 

Unexpected positive feedback:

/

Expected negative feedback:

The ball gets affected by the sandpaper.

Unexpected negative feedback:

The tube isn't steady enough to launch it good everytime.

Makeability score: 2
