IQ Test

This puzzle appears to be similar to the IQ Test 140, also by Jean-Claude Constantin, however in this case the player is given a very short piece of string and a wooden bead to get in the way of a solution. The objective is to remove the ring from the string (the puzzle is shown solved; in the unsolved position, the ring is on the string with no knots or loops).

Made in laser-cut and turned wood, stainless steel, and string by Jean-Claude Constantin. Jean-Claude Constantin lives in Germany, where he designs and manufactures many different wood and metal puzzles, as well as magic tricks.
