Easy Green: How To Make A Water Hippo
What is a water hippo, you ask? It’s a water-saving device for your toilet. I really don’t know why it’s called a water hippo, but I heard it called that once and we’re going with it. Instead of using a brick – or even finding a brick – why not use something you probably already have around the house? I’m using a 32oz yogurt container. You can use any size container that will fit in your toilet and still produce a strong enough flush. I probably wouldn’t go much over a 64oz container. Put a heavy rock at the bottom so the container doesn’t float around and interfere with the toilets internal parts.

i dont really get …. what this water hippo do…. saves a cup of water ,,every time you flush???
The water hippo displaces the water in your toilet. It depends on how large of a container you use. The one that I used in the example was 32oz or 1/4gal saved on every single flush. You can get away with about 1/2 gallon without affecting the flush in a standard 1.6gpf US toilet.
