Electronic toilet paper dispenser
people sometimes tend to use too much toilet paper at one time. I worked at a state park this summer and was putting eight to ten roles of toilet paper in the bathrooms a day, and most of it ended up on the floor. If people had to push a button to get toilet paper then i think it would save some. Even if it was motion censored i think it would help to limit people on how much they use.
Reward: I would just like to have one!
