Next protype is also by using compressed air. We used and old motorbike tyre (Ø60mm) to launch the tennisball (Ø67mm). We used the tension between the flexible tyre and the tennis ball to build up the air pressure.

The tension, created by the Δ 7mm, was not large enough to build up the air pressure to launch the ball properly.

Expected positif feedback: Some air pressure was created.

Unexpected positif feedback: /

Expected negatif feedback: /

Unexpected negatif feedback: Not enough tension to launch the ball properly

Makeability score: 4 (15 minutes)
