VIDEO: German zoo's water bucket camera offers glimpse at how animals drink

COLOGNE, Germany -- A zoo in Germany is offering a different perspective on the importance of water conservation.

The Kolner Zoo in Cologne placed a camera at the bottom of a water bucket to reveal how different animals drink.

A host of animals are featured, including elephants, and a tiger who swatted at the water instead of drinking it.

The video begins with a quote from di Vinci that states "water is the driving force of all nature."
