Step 2: Step 1

clean bottle
put rocks in it
put it in the tank part of your toilet bowl to save up to a gallon of water per flush (depends on how many bottles you have)
<p>That's a smart idea.. I used to do it.. but don't know why I put the bottle away..! I will place it again into the toilet.</p>
<p>You can fill the bottle with water.</p>
<p>I use a 2 liter plastic soda bottle. Works fine.</p>
so simple and yet effective. thanks anthondanthony
