Have fun with this!

It has CO2 in it, which makes it bubbly, which means when you shake it, the bottle fills with CO2.

When you breath in, you are filling your lungs with CO2 instead of Oxygen which gives you a temporary 'high' for like 2 secs. Makes you cough.

Aha, is it a US-only drink? I don't recall seeing one in the UK anywhere.
ty for info.

You can do it with any 2-liter soda bottle, EX: coke..

Just don't shake it up.. anything that spews I wouldn't recommend shaking up.

It has to be a brand new never opened bottle.

Just open the cap, and inhale right fast before it all escapes, squeeze the bottle too.

it feels like you are drowning/suddenly out of breath so you get dizzy and calm.
