Dimensions: 20 x 4 cm + string
Goal: Remove the cord
People who have already dealt with these kinds of puzzles will probably warn to you of their complexity. It is necessary for you to have the courage NOT to demolish it or cheat using scissors! Also, once you solve the puzzle, you have the added bonus of trying to get the cord back into the puzzle in the same state you found it in...It's like two puzzles in one. Which way is harder? We'll let you figure that one out!
A helpful hint: You have to pass the small cord through all the holes in the puzzle, and then try and make a large node to pass the entire wire contraption through.
