This will wake you up: take a plunge into a pool of coffee!
Coffee not your thing? How about green tea?
Red wine pool.
Why is that man laughing? Because he's swimming in sake!
The Yunessun Spa Resort in Hakone, Japan, has 25 specialized pools you can bathe in. Some, like the Roman Bath, Turkish Sauna, the Deep Sea Bath are fine and dandy.
But here's the reason the Yunessun Spa Resort is in Neatorama: it has several specialty spas where you can bathe in real coffee, green tea, wine, and even sake!

it's only dangerous to stupid people who do stupid things, in which case they deserve whatever they get. and as for being wasteful, it is serving a purpose, instead of being poured down a drain, which would be truly wasteful.
have you ever bathed in sake? the next time you take a bath, add a cup or two of sake to the bathwater, and look at what a disgusting brown ring it leaves around your tub. sake (obviously, being alcohol) cleans the skin very effectively, removing bits of dirt ground into your pores.
It seems dangerous and wasteful.
I imagine people with food fetishes would like that sort of thing. Cream with your coffee?
"Look, my vomit completely disappears into this green water"
"That brown stuff's NOT coffee"
