After extracting the tentacle from the mold I tried to inflate it with the needle of a syringe. In the structure there was perhaps some loss that I could not identify. The tentacle swelled only on the left side, not bending as I imagined for this problem (image below).

I thought to speed up the drying process I made the mistake of putting the molds in the oven with the biosilicone. This is back liquid after a few minutes. I moved the molds in the fridge (as you do with a pudding!)

Once extracted from the mold it was very elastic but not enough to be used for this application.

> After some days the tentacle dyed. inside is clear that there's space for the air chamber but the consistency of a fresh biosilicone is misleading. To obtain the right elasticity for the movement of the structure the biosilicone must be very fresh but when the material is very fresh it tends to flake, breaking very easily if it is filled with air.
