Save water in your kitchen

We keep a metal pitcher by the sink for any leftover water or ice from cups, steaming vegetables, etc. and use that to water our plants.  The kids have been contributing to this since they were little, and telling their friends about it when they come over. I put leftover coffee and coffee grounds in the pitcher too, as the plants love this. Metal is great as it won't get broken and you can't see the floaters.
