Body inflation

I've been thinking about doing one of these for a while but i'm also a bit scared if i get the formula wrong, can someone help me with that and provide other tips? thanks

I have already tried and it works well, but the pure vinegar does not taste very good: I had cut it with water just like the baking soda (powder) to make it easier to swallow.
I advice you to do it slowly

Thanks man, do you happen to have measurements of what you did? That’s mainly what I’m looking for but I’m not gonna ignore the other advice you have

No, unfortunately i didn't take any mesurements, i would certainly do it next time ^^

I don't remember, i didn't take any mesurement nor pictures :/
It was more a trying, just to see if it works.
I'll certainly do it again but this time with baking soda pills and fizzy drinks: i think it'll be fun to not be able to control when the pills will release the baking soda and make me inflate
And i'll take pictures/mesurements this time.

It will last for about a few hours depending on how much you take.
