This is my challenge at work. Normally I would use 6 paper cups for coffee and water throughout the workday, 6 days a week. Now I am using my single reusable coffee mug and thermos instead. This saves 36 disposable paper cups a week. I am excited!

The container on the left is the amount of water I used to brush my teeth each time before the challenge. The container on the right is the amount of water I use to brush my teeth each time now! 128oz=1 gallon, now I am using 12 oz.
