Thanks! Wonderful idea that works well. I'm thinking I can put another hook in the ceiling to hook the figure eight knot to if I want to have the door open but have the ball up out of the way. I also used popcorn as a weight instead. I would definitely recommend just buying fishing weights as you almost have to fill the tennis ball for 2 oz of popcorn. It was a very tedious process.
