  • Place the box in the center of the mat.
  • Remove cylinder with 3-finger grip.
  • Arrange cylinders randomly in a line from left to right.

 Start with the left cylinder, carefully lift it and place it in the palm of your hand.

  • “Would you like to feel how heavy this one is?” Return the cylinder back in line.
  • “Now let’s see if we can find a match. I am going to use my hand to do this work.”
  • Isolate the left cylinder, feel the weight
  • Weigh each remaining cylinder until you find a match. Move out of line slightly. Weigh the control again, move match to the side. Weigh control, weigh match. “These two match. They are a pair.”
