Cut a 7-inch-diameter circle out of card stock. Draw a spiral on the circle as shown. Next, use the scissors to cut along the lines you drew starting
on the outside and ending in the center. Use the hole punch or scissors
to make a hole at the middle of the spiral and attach the thread with a
knot. Tie the other end of the thread loosely around the center of the
stick so you can suspend the spiral in the air. Fill the pot with 2 inches of
water. Heat the water until it boils, and then turn off the heat source. Let
the pot sit for 4 minutes. Holding the ends of the stick with the spiral
attached, position the bottom of the spiral right above the top of the pot
so it's not touching the water. Describe what happens.
