Puzzle with a rope and a ring

What do you need:

• Piece of wood 15 x 3 cm.
• Ring of 2 to 3 cm in diameter.
• Piece of string.
• Saw.
• Sandpaper.
• Drill.

This is a fun puzzle with which you can impress people.Take the piece of wood about 15 x 3 cm at the ends and make a small hole where the cord can go through. Drill a larger hole in the middle where the cord can easily go through four times simultaneously.Attach the ring to the cord and make the cord as you can see in drawing two. The ends you can put through the hole once and tie a knot in the rope to make it unable to go back.

The aim of the puzzle. You will see a rope running from one side to the other with a loop through the woods in the middle. The ring is suspended on the left side. The idea is to get the ring on the right without untying the cord. So the ring should be on place C instead of on place A.

If you can’t figure it out, here is the solution

Hint

• If you have thick cardboard you can also use that to create the puzzle. You should watch out that people do not bend the cardboard as it could break easily.
