Hate to argue after all this time, but yes. Yes I believe a piece of duct tape could seal a can for purposes of keeping the liquid inside of it inside. Scotch tape, no, painters tape, maybe, duct tape… definitely yes, especially if I used two or more pieces. But yes one piece I would be confident.[/quote]
I think this depends on what a ‘single unit’ of duct tape is, exactly. I’d say 5 units might be more reasonable, but I’m not sure what the actual units are, so it’s a bit arbitrary (200 units is an entire roll I guess? I don’t know how long a roll of duct tape is).
Presumably we’re just taping the lid back onto the can, but duct tape isn’t actually waterproof in the long term, so using multiple layers seems much more reasonable.
I haven’t actually tested this, but I would bet that a single layer of duct tape would leak after only a few minutes of jostling, if you use several layers then the water wouldn’t reach the adhesive attached to the can+lid itself, so it would last a lot longer. I still wouldn’t call it watertight, but in the short term it would work.
An alternative (that would take a lot more coding work) would be to make it so you can wield or drop a can/bowl/pot and have it retain liquids, the realism issue comes in when you stuff a pile of junk into your bag/pack and start jogging away, even a slightly loosened water bottle will leak water, much less an opened can.
