Place two sticks parallel for the runners. Glue additional sticks crosswise over the runners to form the bottom of the sled. Cut another stick in half and glue these close to the one end of the runners at a 90 degree angle. This forms the back of the sled. Using felt add a small pack to place on the sled.
Place sleds at the top of an inclined board.
The sleds are released at the same time. A board in front of the sleds that can be lifted up is one way to make sure the sleds are released at the exact same time. The first sled to reach the bottom of the incline wins. Use the table below to keep track of the winners.
