Wondering if somebody has done inflation in Michigan. What if you could inflate yourself so big with helium and could float? How far up and how big would you want? And this is a side question for females how much would you inflate your chest?

No, it's impossible because helium is not light enough, and in fact even hydrogen isn't. The density of the human body is about 700 times that of air. In order to float, even with a vacuum inside it, an object that dense would have to be 700 times larger in volume than it is now, which means you'd need to increase about nine times in each direction to achieve that. My uninflated volume is eighty litres or so. A sphere of my weight containing only vacuum would need to be over fifteen feet in diameter to float. In fact, helium and the lighter hydrogen both have weight, which means they'd be even bigger. Therefore it can't be done under normal atmospheric conditions on this planet.

However, i happen to be writing a story set somewhere it would be possible, so watch the stories section.

Its funny how alot of these FANTASY threads turn into logic and "well that cant really happen in real life" threads lol

Well they do when i'm around! Sorry, i'm probably being a bit of a killjoy. But there are places in the solar system where this is possible and given that this proclivity is not the most realistic one we could have, why not just imagine a spaceship taking you there? It's not much of a stretch. Well, it will be once you arrive i suppose.

Ok so what's better thn a spaceship taking u where it cud happen? If our view of how magic cud be were realistic. Thn it wudnt matter about physics lol. But that's a whole different ball of wax now ain't it? Lol.

Before we attempt space travel, let's master spelling.

Nice one, Dan... Agreed :D
