  1. “Biodegradable” is a bit of a scam – check this out… ““It’s well-intentioned but wrong. A lot of plastics labelled biodegradable, like shopping bags, will only break down in temperatures of 50C and that is not the ocean. They are also not buoyant, so they’re going to sink, so they’re not going to be exposed to UV and break down,”

  2. Surely biodegradable is better than dissolvable. no? “Polyvinyl alcohol (PVOH), of which MonoSol films are comprised, is a colourless, odourless and non-toxic polymer. It is produced by combining and re-arranging the three basic elements – carbon, hydrogen and oxygen. These elements come from ethylene gas – the same gas emitted by fruit and veg as it ripens – and acetic acid (known as household vinegar in its diluted form).”

  3. This foam does it – but does it turn back into crappy foam stuff when it dries out again? Not sure if this is a good idea or not tbh.
