1. First make a paper cone to line the funnel. Cut a circle out of the construction paper. Use the bottom of a bowl for a pattern. Remove a quarter of the circle, pull the sides together until they form a cone, and tape them. Leave a small hole at the tip.

2. Tie a string around the lip of the funnel. Use other string to suspend the funnel above the table from a light fixture or the handle of an open cabinet door. The funnel should hang a few inches above the table surface.

3. Place the black paper under the funnel, and put the paper cone into the funnel.

4. Block the funnel’s tip with a finger and pour in some salt.

5. Remove your finger, push the funnel gently, and let it swing. The salt should form a pattern on the paper.

6. After the funnel stops, pour the salt back into the funnel. Try pushing off the funnel again in different ways and see what other patterns it forms.

7. To make a picture that you can save, brush a thin layer of glue over a large sheet of black paper, making sure that every area is covered. Then follow directions 4 and 5. Let your paper dry completely before removing it from the table.
