More of a mathematical, kinetic sculpture, shape-maker this item has interesting and puzzling properties that allow for sculptures to be created.This is an extremely rare handcrafted product by F Floweday Designs that ceased in 1991. This seems to be the forerunner and more complicated version of the Octyflex, which can be seen in the Jerry Slocum museum. A unique piece that Iohave not seen another version of anywhere.Packing has seen better days but the puzzle and instructions are perfect.Trac...

This is a seminal vanish puzzle originally created in 1990 by Robin Debreuil from Debreuil Digital Works in Manitoba Canada --- seminal because it was an early puzzle application of Flash.  In 2010, Magic Moments With Class produced it in large hard copy format (15 1/4" x 5 3/4") as The Perplexing Puzzle Paradox.  13 characters change to 12 characters and a lump of dog poop!  The puzzle comes complete with a 4-page brochure providing classroom lessons based on the paradox.  The puzzle is in ...

One Piece Puzzle - a bit of a misnomer, as it is no more a 1 piece puzzle than is a Rubik's Cube. A number of bent "L" shaped metal pieces articulated by links of plastic. You are supposed to either flex them all out flat or make a cube out of it. And yes, there is a bit of a trick to it (I never did get the "cube" part of it). Exchange from Harry L. Nelson , concept by Engel. Not sure who made it, though.

"Jack In the Box" is an eerily shocking VANISHING VOLUME packing puzzle, designed by puzzle designer (Wave Links, Double Tour, etc.) and perennial International Puzzle Party attendee Rod Bogart.  Amazingly, the eight solid aluminum blocks fill the acrylic container (first illustration), yet they can be rearranged in the container such that the black six-pronged stand may also fit (second illustration)!  A video describing this puzzle, as presented by Rod at the 15th Gathering for (Martin) Gard...

This is a very colorful hexahexaflexagon with interesting patterns that was available commercially for just a very short time in the late '90's.  Complete in original packaging with instructions.  Never played with.I will ship within the US at the lowest ground advantage (new terminology replacing "first class") package rate for around $5.25 (Regrettably, the package will be too thick to ship as a letter.), or if preferred, at insured priority mail pricing (likely from between $10....

"Camel Puzzle" and "Horse and Cow Puzzle."  Both of these folding puzzles were produced in 1941 (thus making them 81 years old!) by the Strombeck Press of Moline, Illinois.  Two years later, Harold Edborg (owner of the Strombeck Press) was granted patents for each puzzle, US Patent 2327876 for the Camel Puzzle and US Patent 2327875 for the Horse and Cow Puzzle.  Both of these puzzles are in MINT condition!  As such, I didn't want to unfold and try to flatten them for a photograph.  However,...

University of Rhode Island (emeritus) mathematics professor Dean Clark used vanish puzzles extensively in his non-majors math class, "Mathematics of the Unexpected."  The Missing Pumpkin is one of his designs.  It was published in the October 30, 1997 issue of the Providence Journal-Bulletin newspaper, just in time for Halloween.  (Providence is the capital city of Rhode Island.)  I am offering the complete 8-page "LifeBeat" section of the newspaper.  The Missing Pumpkin vanish puzzle appea...
