  1. ...'s take the density of air at 1.26 kg/m³ and helium at 0.179 kg/m³. Then per cubic meter of air...of 14.6 m or more and not have it collapse, and fill it with helium , it could float away. Double the thickness, you'd...

  4. That's funny, we released helium balloons with small keychain lights on them so people would think they were UFOs.

  5. Depends on how full they are... as they rise, the outside pressure decreases, and - this expands the balloon, so... they can pop.  Or, they can float in the breeze, and eventually lose their internal gas, and drop back to Earth.
