Hi, I am intending to do this art experience with third grade kids. I want to give them a scientific explanation of why the paper stays coiled. Can you help? Here is the activity. Paper Coil Materials: construction paper permanent markers dowel or pencil or broom handle bowl of water towel duct tape or tack (use adult assistance if using a tack) Procedure: 1. Cut paper into strips about 1/4 inch wide and 5- 10 inches long. 2. Decorate the paper with markers on both sides. It is fun to make it look like a snake. 3. Dip the paper into the water. 4. Put two fingers between the paper strips and release the extra water so the paper is not dripping. 5. Duct tape one end of the paper strip to the dowel, pencil or broom handle. 6. Wrap the paper strip around going along the dowel, pencil or broom towards the end. It will look like a long snake coiled around the pencil. 7. Tape the ends and then put the dowel in a place where it can dry for several days. 8. When dry uncoil the “snake” and notice that the paper will remain coil
