Human Tower Building
If you enjoy watching cheerleaders form human pyramids, you'll love the castellers, people who compete to form giant human towers at festivals around Catalonia, Spain. Castellers form a solid foundation of packed bodies, linking arms and hands together in an intricate way that holds several tons and softens the fall in case the tower collapses, which is not uncommon. Up to eight more levels of people are built, each layer standing on the shoulders of the people below. The top levels are made up of children and when complete, the castell resembles a human Leaning Tower of Pisa.
