Beyond the coolness of being able to play pool while in a pool, there's also the added bonus of you being able to make as many pool-related puns as you want if you get this crazy thing installed.
Yes, this waterproof pool table works both in and out of the pool. It's perfect for when you want to shoot pool outside but also want to cool off in the water. It won't come cheap: the asking price is $6,500. But it's certainly cheaper than continuously ruining non-waterproof pool tables by submerging them in a pool, isn't it?
