How do I source a transparent scuba tank for a cosplay prop?
I’m working on a cosplay that uses a wearable scuba tank backpack as a key prop. The tank needs to be fully transparent and molded with the domed shoulder and neck integrated, basically the exact shape of an AL80 (7.25" diameter, 26" tall) but clear.
I'm wondering if there's already something out there, a carboy, water jug, lab vessel, anything that naturally comes close to that shape and size in clear plastic. It would also need some way to open from the bottom or top to put stuff inside. I'll be mounting it to a real scuba backplate so it needs to hold up structurally.
I've thought about it and a 2 liter soda bottle is actually the right shape and concept, just nowhere near the right size. Something like that but scaled up is exactly what I'm looking for.
Has anyone achieved this seamless look for a prop before? Reference image of the harness attached. Any ideas appreciated!
