Crafts and Games- Block Puzzle

Here is another brainteaser from pioneer days.

You’ll need:

• a block of wood 4 inches long and 1 inch wide
  
• drill
  
• a piece of heavy cord 12 inches long

1.  Drill two 3/8-inch holes in the piece of wood, one at each end.

2.  Fold the cord in half to make a loop.  Thread the loop through one hole, and then run the ends through the loop and through the other hole.

3.  Tie a tight knot in the ends of the cord.

4.  The object is to remove the cord from the block without untying the knot.
