Why didn't I think of this?!

Flip-It bottle caps are a system designed to eliminate product waste. They state they are designed for 95% of bottles used in households. Once a bottle is nearly empty you attach the correct cap, which uses gravity and a 3-prong stand to keep your bottle upside down. These are effective, very easy to attach as well as use. The only thing I would change about this product is the sets which are available in various sizes and configurations, do not include as many stands as I'd like. However you can order them separately. These definitely are a time and money saver!
