The Jaipur Foot has changed lives in India, Mark Magnier writes for The Times. The low-cost prosthetic device can be attached to an artificial leg of any length, allowing amputees to walk. More than 1.2 million devices have been handed out to impoverished people over the last three decades.
Want to see it in action? The civic group behind the Jaipur Foot provides the video above, which shows people running, climbing and riding bicycles with the device. It also shows how the simple prosthetic is made. Bonus: The video even has the stirring musical strains of Eastern strings.
