Wow! I'm hot on the trail of a new eco-friendly tip today. Someone just told me that you can save water by putting a bucket in the shower before you start running the water. I'm not sure how this works, but it must be something like those plastic laundry balls. When the bucket is in the shower, you probably don't need to use as much soap to get clean, and so don't need to rinse as long. I'll let you know as soon as I find out more. Meanwhile, don't forget to take that bucket into the shower with you, because it doesn't hurt to be on the safe side!
