I saw this and though I don't think its a long term proposition, interesting what this guy did to escape the heat making a pool from cardboard

great idea, but with the cheapness of marine ply here in Thailand I think it would be a better option. I'm also not too keen on the idea of having the wooden supports inside the pool unfinished, that is trouble waiting to happen on so many levels, especially if kids are involved. Definitely a thought starter. Whereas I think that my 'fish tank' for the kids has been worth its weight in gold for less than 2000 Baht.

I agree with you Oz, the lack of external support worries me greatly.
