Imagine turning up to a festival and finding that someone was selling something called Hot Dog Water for over £20 a bottle.

If you had any sense, you’d jog on.

Especially when you realise that the keto-friendly, gluten-free beverage is just…a hot dog in a bottle of water.

It sounds absolutely rank, regardless of price. But what if you were told that it something of a miracle juice, able to help you lose weight, increase brain function and look younger.

Would that tempt a £20 note out of your wallet?

Well, it did for a load of people at a recent Car Free Day festival in Vancouver, Canada. The Hot Dog Water booth also advertised the fancy bottled water as being a great source of electrolytes – always useful on a hot, sunny day.

A Hot Dog Water flier read: ‘With the demands of city life and high-stress jobs, electrolyte imbalances are all too common these days.

‘We believe Hog Dog Water can help restore the body’s homeostasis after an electrolyte imbalance.

‘By balancing the state of your body’s multicellular organisms, Hot Dog Water helps you achieve max capacity for biological defences so you can fight both infection and disease,’

So useful.
