First shot of the "my first rotomolder" so i decided to go for something a bit more different to plain net; a bottle of irn bru.

All was going well until about 2 minutes of turning when the Jcast seemed to just slip off the middle section of the bottle and clump together. Perhaps not enough to grip onto on the smoother sections of plastic?

Second Attempt

Decided to first manipulate the bottle with a heat gun to hopefully allow more grip in the smoother sections and also decided to add some red food colouring

However the same problem as the first occured and the Jcast fell together. Also the food colouring caused a bubbled effect on the hardened plastic

Roto molding fail or roto molding win?
