What's a Burr Puzzle? This wood crafted, precision-made puzzle of intersecting cuboids supposedly resembles a burr seed (that famous inspiration for Velcro) upon completion. Not only is the name interesting, but the puzzle itself has been an inspiration to recreational mathematicians worldwide - just ask Bill Cutler, author and puzzle enthusiasts whose seminal works, Holey 6-Piece Burr! and A Computer Analysis of All 6-Piece Burrs have captured the hearts and minds of metagrobologists* everywhere. In this classic six-piece Burr, three sets of rod pairs need to intersect with each other to properly to solve the puzzle. (*metagrobology is the study of puzzles. If you get stuck with this puzzle, Bill Cutler lives in Illinois, USA. Just ask around once you get there, he is fairly well known and surely he'd be happy to help!) Dimensions: 2 1/3" x 2 1/3" x 2 1/3"
