Here is my last video. It's the first time that it works so much. Firstly, i wanted to wait the psi wheel to stop (there is always a little air flow when you place the bowl) and use my hands (and i wanted to make it turn in the other direction). But when i have seen that it didn't stop, i decided to continue the mouvement without my hands, and it worked well. We can really see that the psi wheel stopped to turn, then continue the mouvement.
