Because the tyre didn't create enough tension to build up the air pressure, we tried to improve it with an elastic around the tyre.
By launching it, we achieved a distance of 4m.
Expected positif feedback: More pressure was created using the elastic.
Unexpected positif feedback: Shoots remarkably further than the previous version.
Expected negatif feedback: /
Unexpected negatif feedback: Shoots not as far as we wanted it.
Makeability score: 5 (15 minutes)
