Trappe continued to experiment in cluster ballooning flights. In 2011, he replicated the floating house from the animated film Up for a National Geographic television program. [28] On July 6, 2015, Daniel Boria of Calgary, Alberta, Canada, tied about 100 helium balloons to a garden chair and flew over his city in a publicity stunt.
Balloon Experiments with Amateur Radio (BEAR) is a series of Canadian-based amateur radio high-altitude balloon experiments by a group of amateur radio operators and experimenters from Sherwood Park and Edmonton, Alberta. The experiments started in the year 2000 and continued with BEAR-9 in 2012 reaching 36,010 metres (118,140 ft).

Cluster ballooning is an extreme sport and a form of ballooning where a harness attaches a balloonist to a cluster of helium-inflated rubber balloons. Unlike traditional hot-air balloons , where a single large balloon is equipped with vents enabling altitude control, cluster balloons are multiple, small, readily available and individually ...
They also use hydrogen as a lifting gas instead of helium as it is a renewable resource. The balloons reach 38 km (24 mi) on average, taking a few hours to reach that height. The air pressure this high causes the balloon to keep expanding, reaching 10 m (33 ft) from an original 2 m (6.6 ft) until it bursts.
Using lead foil, Adam and Jamie constructed a cube-shaped balloon with 10-foot (3 m) edges out of lead. Even without pure helium inside it (a mixture containing air was used to limit buoyancy and reduce the possibility of tearing), the balloon was buoyant enough to support a basket along with some ballast.
Project Excelsior was a series of parachute jumps made by Joseph Kittinger of the United States Air Force in 1959 and 1960 from helium balloons in the stratosphere.The purpose was to test the Beaupre multi-stage parachute system intended to be used by pilots ejecting from high altitude.
A Helikite lifting a gyro-stabilized camera. The Allsopp Helikite is a kite balloon or kytoon designed by Sandy Allsopp in the United Kingdom in 1993. [1] This Helikite comprises a combination of a helium balloon and a kite to form a single, aerodynamically sound, tethered aircraft, that utilises both wind and helium for its lift.
