Inflatables filled with hydrogen?

If you did want to use hydrogen, where would you get that much? It would take ages with electrolysis and be expensive. If you did attempt it, make sure it's 100% hydrogen. Don't mix it with air otherwise it can explode. To be honest it would be better to just use air while in water. Then it would feel like it's floating without the danger.

Might as well just use acetylene and really put on a show...

Yeah I'm not really into murdering inflatables (or balloons for that matter) so that ain't gonna happen with me.

Well yeah, I know how it works. With even the slightest spark the hydrogen would react with the oxygen and go boom, to put it simply. Also, that much hydrogen could be made with electrolysis, it would just take a few minutes. Grant Thompson "The King Of Random" made a water electrolysis machine that works rather well. You'd just have to be very patient.

I still wouldn't really recommend it. If you're trying it, be safe and try it outdoors.

Personally I would just tie helium balloons to an inflatable depending on the size, but we all have preferences.
