    Traveling an average of 22 mph (35 km/h), Couch used plastic bags filled with 75 litres (20 US gal) of water as ballast against the 105 large helium balloons tied to his lawn chair. Like Walters, Couch had a BB gun on hand to shoot the balloons in order to initiate descent.

In aeronautics, a balloon is an unpowered aerostat, which remains aloft or floats due to its buoyancy. A balloon may be free, moving with the wind, or tethered to a fixed point.

    A balloon can only have buoyancy if there is a medium that has a higher average density than the balloon itself. Balloons cannot work on the Moon because it has almost no atmosphere. [14] Mars has a very thin atmosphere – the pressure is only 1 ⁄ 160 of earth atmospheric pressure – so a huge balloon would be needed even for a tiny lifting ...
