Heya just wanted you let you know how i inflate!
First i slip into my one piece swimsuit and insert the hose up my bum. Then i get 3 balloons and pull them over eachother so i get 3 balloons in one! I inflate them and connect it to the hose. All the air thats in the balloon fills my belly up nice and round!
As im typing this i am still in my suit! Need to wait till i deflate a bit else i cant get out of it ;)
If the swimsuit is tight enough (it'd be neat to stuff the balloons into your swimsuit and then let the natural tightness compress the balloons to force the air into you--as the balloons get smaller, you get bigger!) or if you squeeze the balloons somehow, you can do it.
I echo the "play it safe" part, though. If you feel pain, STOP.
The balloons do deflate pretty fast but i hold the end of the balloon with my fingers so i can regulate the flow! Like the thight swimsuit idea.
That's curious. In the past before I had other equipment, I was never able to get the balloons blowback to inflate me. It was never enough pressure or something, I don't know.
Congrats on your method however, and make sure to play it safe and that the balloons don't deflate with too much pressure!
