    The pressure vessel gives me concern. Two part epoxy to glue bottles together seems a bad way to go. Some of the vessel is rigid where it is epoxied, some of it flexes where it isn’t and there’s a whole host of different stresses in between. Maybe a two liter soda bottle with a shape designed to withstand pressure, and not the thinnest layer of PET intended to be a water carrying vessel only.

    It doesn’t take much compressed air at 3-5 bar to fuck someone’s day up pretty bad.
