Seriously guys, get your s**t together. Water of different temperatures can legally touch. It's okay, I promise.
I have no idea why anyone would need this, but either way....
Actually, they should have, I was just being faucetious.
That's because British people only have two uses for water: hot water for their tea, or cold water for splashing on their face after getting tipsy at the pub. #stereotypes
