Cup stacking is a high-speed assembly and disassembly of pyramids made of plastic cups.
The idea of arranging glasses came to the physical education teacher of one of the American schools in 1981. The sport began to gain popularity quite quickly and in 1990 the first national championship was held. In 2001, the World Cup stacking Association was established.
To play cup stacking, special sets of 9 or 12 glasses with holes in the bottom are used, which allow you to quickly disconnect the glasses.
There are several assembly combinations and they are all executed on time. To fix the time, special timers are used, which were created for cup stacking, but are also used for speed-cubing.
Rules: the smallest pyramid is built from 3 cups, the largest — from 10.
the most popular combinations are 3*3*3, 3*6*3 and round( 3*3*3 then 6*6*6 then 1*10*1)
The biggest competitions in are cup staking the World Championship.
