Ice ball bottle
An external ice housing: long cooling, no dilution.
02Approach
We moved the ice out of the water and into a clear, sealed channel down one side of the bottle. The channel is lobed to the ice balls, holding each in its own pocket against the bottle wall, which carries the cold through.
03Result
A sealed housing model with the bottle body, cap and ice channel resolved, so the cooling idea can be prototyped and tried.
