From the side the water fountain looks like most others: a spigot shoots arcs of water from a corner when you press a button somewhere. But when you face the EZH2O water station — a bottle-filling station — you see that the spigot in the corner is not the only mechanism on the wall.

I’ve been carrying around aluminum or hard plastic bottles for years, and am always annoyed when I have to replenish from a water fountain that doesn’t shoot water in a high enough arc so that my bottle can fill to the brim. With the EZH2O, all you have to do is place a bottle in front of the motion sensor in the back panel, or simply stand it on the grey plastic platform, and water will come down in a straight and soft stream.

As your bottle fills, a little meter in the top corner of the panel tallies how many plastic bottles have been saved by using reusable bottles. Also, the bottle filling station has a WaterSentry filter (and a light in the top right corner that shows when it needs to be replaced). So far, I have only seen these in Cornell’s Olin Library, both in the stacks and the basement. Hopefully they will spread to every building at Cornell.
