Vanishing Line

Vanishing Line

Vanishing Line Look at the 2 pieces of wood and you will clearly see 13 horizontal lines. Yet flip the frame upside down and there are only 12 lines!  How can this be? Some call this the “Sobriety Test”, yet there is an interesting math basis for the puzzle. The idea for this wonderful illusion came from one of Martin Gardner’s recreational math books.  Good for messing with friends, or a coffee table/bar type item, or effective in the math classroom also. Pieces are made from 1/4″ thick hardwood, either maple or cherry.  Base is made from floorboard material so it is very strong. Size of the puzzle in base is 7″ x 3.25″ x 0.6″

Are you a person who loves a good mystery? Me too, I also love puzzles and you should know that the two are now being combined to make the life of a mysterious enthusiast more challenging. These original puzzles give the right name to mysterious puzzles. Use the book to run the story, but to find out who finds the answer in the puzzle itself, you can not solve the mystery without it. There is just a little more research needed to make the puzzle not match the image of the puzzle in the box!
