Ok, so I finally have some money. I was gonna buy a motorbike, but I think it can wait.
I'm building a sensory deprivation tank instead!

Here are my plans.

I will use this thread as a WIP for anyone else that may want to build one.
As well as get some advice from people in case I'm doing something wrong.

These plans are subject to change due to materials etc.
I was going to use epoxy resin, but it seems that it may contain a toxic chemical (Bisphenol) which inhibits hormones. So I'm probably going to go with a normal pool/pond liner of very high quality.

The "B" part is for if I use water bed heaters. "A" is for if I use an external heater (more likely, and more environmentally friendly coz it doesn't have to be on 24/7).
