The ball is actually pretty low to the ground. It's not necessary to fill the entire ball since you only need to fill out a certain amount of the air inside the ball with helium. If I enter the ball while it's deflated and has little oxygen inside and then close it and start releasing the helium then that should completely replace the air inside so even if only a small part of the ball was inflated with the helium it should still be enough since there is almost no oxygen inside to begin with. When I went inside with my helium tank and I was practicing how to zip up I feel like I couldn't breathe so I had to get some oxygen inside that last just long enough for me to comfortably put the zipper all the way up. If you have this sett up and you enter you will discover that there is almost no oxygen inside even if the zorb ball is sitting there with the zipper open. I
Like you said, there's going to be very little oxygen in that when you get into the deflated ball. But is it going to be uncomfortable inside that closed ball while you wait for it to fill up with helium? You don't want to be stuck inside that getting feelings of suffocation while you wait on enough helium to fill it.
At least with the exit bag, the CO2 won't build up, so you won't feel uncomfortable. Plus you fill the exit bag with the inert gas before you pull it down. With this you can't wait for it to fill up first, can you, due to O2 potentially getting in?
It seems like a giant exit bag that you could potentially lock yourself into.
good idea, I just guess you have to make sure the gas stops filling the balloon before it gets too tight and about to explode.
Yeah, can those things blowout if there's too much helium in them?
This is amazing. I don't think suffocation is possible because these are used for play, so there must be air inside (vented somehow?) Could nitrogen be used? I've considered helium but have been hesitant because I know they water them down somehow now. Anyone is US know where to get pure helium?
Suffocation is possible, as they're airtight. They pump them with air after each ride. Like you said, they usually recommend staying in them for ~15 mins.
