The River Thames is a river in England that runs through the center of London and flows out to the North Sea. It is considered the cleanest river that runs through a major city. In an effort to keep the river clean and show people how important the river is, the Zoological Society of London developed a virtual reality device that takes you through the river to see the wildlife. The river includes all kinds of creatures like pike, eels, seahorses, bull sharks, grey seals, and even dolphins and whales on occasion. Below the picture is a video about the virtual reality experience of the River Thames.
