This was a really easy toy to make for the boys. I picked up these buckets for .50 at the dollar store, cut down a piece of pvc pipe to go under the board and cut down a piece of primed wood. I drilled holes in the wood and attached the pvc pipe with a nut and bolt. I also drilled one hole in the bucket to attach it to the top end of the plank. That too was secured with a nut and bolt. I covered the bottom area in duct tape so the kids wouldn't get splinters. All sorts of things have been flying in the air! When the weather gets nicer, we'll move it outside for some water balloon fun.
