The young scientists of the world have proven themselves truly impressive people—inventing technologies to improve the accuracy of prosthetic devices, developing video-audio memory aids for dementia patients and improving switch designs to prevent train derailments. These are just three of the top 15 projects competing for the grand prize in the inaugural Google Science Fair final tonight, which we’ll be live streaming at 7pm PDT at youtube.com/googlesciencefair.

Back in January, we launched the first Google Science Fair in partnership with CERN, LEGO, National Geographic and Scientific American. We asked young people from ages 13-18 all over the world to submit projects online that were creative, inspiring and groundbreaking. Ten thousand students from 91 countries submitted 7,500 projects, from which our international team of judges selected the top 15 finalists.

Today, those finalists are at Google headquarters in Mountain View, Calif. where they’ll present their projects to a panel of science luminaries, inventors and Nobel laureates. The winners will receive amazing prizes including $100,000 in scholarships, internships at Google or our partners and a National Geographic Expedition to the Gal├ípagos Islands.

So pull up a chair in your home laboratory and tune in to a live stream of the first Google Science Fair to find out which budding young Einstein will take home the grand prize. The event begins tonight, Monday July 11, at 7pm PDT—watch at youtube.com/googlesciencefair.
