10-storey high 'sky pool' suspended between buildings Personally, I can't understand this concept. Even the article is messed up. In the opening to the article, it says the pool is 25m, then soon after says the 5m x 3m pool, which will hold 375 tonnes of water. 375 tonnes of water is 375 cubic metres, my maths must be bad cause I can't figure out how all that water is gonna get into even a 25m pool. Anyway, why would you do this? Would you dare swim in it, 10 storeys up?
