HHhhmmmmm....Now you just need to figure out how to inflate like a balloon, but stay on the ground.

it comes in air variety for a less floaty experience.

First off, I love the way this sentence is made, almost as if the slogan has a pun included in it that I can't help but laugh at it XD Hahahahahaha.....Ahh sorry...

Second, okay, I mean, does your character prefer to float when inflating like a balloon, or stay on the ground??? And if there's different air qualities and choices in terms of balloon/air inflation, what other types of air would there be for different types of air inflation potions?? Would it be the density/weight of the air?? The form you would end up when inflating/swelling up??? The...Uhhh....different type of gases injected into the potion???
What kind of Air Varieties would there be???

I actually like both equally. Using helium to become lighter than air and floating is a lot of fun. But only really good indoors. Using air is good to just be inflated like a big balloon.
As for my potions. Most of my inflation type potions can either be Air or Helium. They result in the same shape its just do you want to float or not. If you want to get very specific the helium version actually is an air helium mix so it just the right amount of lift.

Huh...ONly Air or helium...I see...I thought there were other gases mixed into the potions to get the same effect....Alright then....

I guess it comes down to what you say "Lift" or "density/weight" of how much you wish to float to a certain point...And yeah, I would agree to do it indoors, I can't imagine having to do it outside and literally float into the extremely cold outer space if you ask me.
