Don't throw out the water your boil your eggs in?

Don't throw out the water your boil your eggs in. This water contains tons of calcium that your plants will love. Just let the water cool and dump it on your plants. I also save my egg shells, rinse them out real well, smash them up then mix them with dirt and/or potting soil before planting any plants. For someone who doesn't have a green thumb, I have had great success with this.
