Paddle Block Boats

This weeks project was paddle block boats. They are very simple and fun. You need one big block of wood, one little block (we actually used small blocks from the boys wooden blocks), two nails and a rubber band. You can see in the picture how to put it together. You just twist the little block in the rubber band as much as you can, put the boat in water, and watch it go! I think it's good for kids to see there are ways you can make things move without batteries or electrical cords.
