Directions This activity is best done outside. Make a hole in the bottom of the paper cup. Make another three holes around the rim. Suspend the cup from the string by threading the string through the holes and tying it to an overhang or branch. Spread the brown paper below. Now fill the cup with sand and gently push it so that it swings in small circles and arcs. The sand will pour out and make patterns on the paper below. Reuse the sand to repeat the activity. If you’d like to create a permanent design, dribble glue onto the paper in desired shapes before swinging the sand.
