Keva Planks

Keva Planks are practically magical (but there's an explanation…), all maple, made in the USA wooden building planks. One of the most ingenious toys of our time, Keva Planks use two physical/mathematical properties to allow you to build towers and structures of amazing proportions (world record at time of this writing = over 51 feet!!!). Good old gravity, the same force that keeps us all from floating off into space, holds the structures together. KEVA planks appeal to adults as well as children. Architect firms have held building contests. Preschools use them, elementary schools, gifted children's programs, children with special needs, corporate team building and more. Kids do not outgrow KEVA planks.The magical proportions that make Keva Planks fit together in amazing ways are related to a discovery by Leonardo Fibonacci in the 12th Century. He was an Italian mathematician who discovered a simple numerical series. The mathematical relationships from his series show up incredibly throughout nature, architecture and art.
