Giant Helium Manned Balloons

Manned performance balloon is also called a low-altitude helium manned balloon. It is a kind of tethered balloon. It works by filling a balloon with enough helium, driving the balloon to take off, and hanging a large ring at the bottom of the balloon to make 1-2 or even more dancers to perform in the air, and a number of wire ropes are tied around the ball to fix it to the ground. Giant manned performance balloon is a manned balloon project created by Everrich Art-balloon in China.
