How I inflate myself(not a real inflation)

I have been experimenting with different ways to make some type of inflatable suit type thing. I took a excercise ball and put it under my shirt and pumped it up and it was ok but It took a while and recently I was experimenting with a large trash bag,a belt with that texture that you can stick holes through all around and an automatic airpump. I've only tried this with like making some type of inflatable pants but they aren't really pants lol but What I did first was I took a large un-used trash bag and put it around my legs and pulled it all the way up to about my waist. I then took the automatic air pump with a hose connecting it put it in the bag then I took a belt and wrapped it around the hose and the bag to keep the air in. I flipped the switch and watched it inflate and also if you happen to have a thing for like latex or something like that and your air pump has some type of reverse mode you can reverse it and suck out all the air giving you some tight latex looking suit.I do realize this might have been posted before and I'm probably not the first to come up with this idea and also my grammar is terrible because I just got back from the dentist(teeth pulled) and the pain killers I have to take are making me really tired.
