  1. Remove flaps from the box

    With the scissors, remove all the flaps from the top of the box. It should be completely open.

  2. Poke holes in the plastic cup

    With a round skewer or a screwdriver, poke a hole in the center of the bottom of the cup. Then poke two holes opposite one another along the cup's rim.

  3. Secure the marker in the cup

    Place the marker face-down through the bottom hole in the cup. Secure it in place with clay.

  4. Poke holes in the box

    Poke two holes next to each other in the bottom of the cardboard box.

  5. String the cup to the box

    Thread the string through the two holes in the rim of the cup. Tie the string through the holes in the box so that the cup hangs level and the tip of the marker just touches the surface.

  6. Add weight to the cup

    Fill the cup with small rocks, marbles or other heavy objects.

  7. Place paper underneath the marker

    Place a piece of paper underneath the marker to record movement.
