Calculate how much helium you'll need to lift your camera

by liz |

In the US, helium costs ~180 dollars for a large 240 cubic foot tank, or ~60 dollars for an 80 cubic foot tank. 80 cubic feet (click for image -- 'small' size) should get you 2 flights with a 4-5 foot diameter balloon, enough to lift a camera. For mylar balloons it may only last one flight, but if you seal them well, you should be able to keep the balloons inflated in a safe place for reuse for several days.

Calculate how much helium you'll need to lift your camera rig with this handy table: http://www.chem.hawaii.edu/uham/lift.html
