Some guys decided to arrange a strange competition between dark and light beer: which one will fly higher to space?
They chose a convenient location, prepaired equipment and assembled "space modules". The first ball was produced in America in 1982 to be intended for sending some equipment to stratosphere. A parachute is attached to the ball, it provides safe landing of the equipment when the ball breaks under the pressure of gas from inside. In theory it must happen at the height of 20-30 km.
And this is a ball from China.
Lifting capacity is controlled by a dynamometer. It must show traction of 2 kg. The beer can will be sent empty, otherwise there wouldn't be enough trasction.
