thats a cool idea. u would probably need a lot i would think maybe like 5 or 6.
U could use less if u pumped them up to like 50 psi.

i dont think more pressure in the floats would give more floating power. then again, i dont know too much about this stuff

i think it would beacause air is less dense than watter so by increasing the pressure of air in the flot u increase the volume of air there for makeing it more boyant

i think the the weight of the air probably isn't to much of a big deal. the boyancy probably over powers it.

Helium probably would work well, Hydrogen would be even better, just stay away from sparks

lol, the only source of gas i have is a bike pump. i would rather not pressureize them at all. would that be a problem?

the only problem is you always think of things and never start them.
