Sensory Deprivation Tank

never heard but sounds cool

Sensory deprivation....

Yogi is aware of these devices....BUT  here in Vietnam you can improvise.   
All you've got to do is marry a local, support her extended family, bankroll their business plans and then begin a regime of heavy drinking.

Don't worry......give it enough time & you'll be deprived of everything.

They're also called flotation or isolation tanks or pods. They have one up in Hanoi, just wondering if they'd made it down here yet 🙂

I looked at starting a business doing just that, but the cost of the tanks was just too damn much.

Can I ask how much was the pod to use per hour.

I don't know, I'm afraid. I've just seen them advertised online, I haven't actually been there!
