If you use this method when showering you can save tons of water and tons of money on your water bill.
This technique was developed by the navy as a way to save water on ships. They did this because when they were at sea they cold only hold so much water. This saved more for drinking and cooking.
Step 1: Lather Up
First jump in the shower and turn the water on. Once you're all wet turn the water off. Now take your soap, shampoo, conditioner, etc. and lather up.
