Water Wheel

Materials:

• 2 plastic plates
• 6-8 ounce plastic cups
• 2-3 ounce plastic cups
• 1 dowel (approx. 12 inches long)
• string or ribbon masking tape

Materials for wheel base:

• about 6 milk or juice cartons (1/2 gallon, rectangular, waxed kind)

Directions:

1. Punch holes in center of plates and center of bottom of 3-oz. cups.
   
2. Place plates bottom to bottom, attaching them with rolled-up masking tape and also taping them around the inside edge.
   
3. Space 8-oz. cups around edge of the plate. Tape so that all cups catch water in the same direction.
   
4. Put dowel through center of plates. Tape 3-oz. cups bottom to bottom. Put dowel through center of cups. The small cups act as a take-up reel. Tape a long piece of string or ribbon to the take-up reel.

To use the wheel:

1. Make 2 stacks of 3 milk or juice cartons laid on their sides. (Use more or fewer cartons depending on the depth of your sink.) Tape cartons together, preferably with duct tape.
   
2. Punch a hole in top carton of each stack and insert dowel ends into stacks.
   
3. Place entire base/wheel set-up into sink and run water onto cups on wheel. As wheel turns, dowel and take-up reel should turn, too. (Tape plates or take-up cups to dowel if necessary.)
