When I was a lad, the science fair was a dozen schools. The Google Science Fair
has students from around the world, which means I would be unlikely to spend 3 minutes looking at the problem, guess because I had to get to another event, and still place second in the physics competition.
The good old days.
But the prizes are better than the textbooks I got also. So if you're ages 13 to 18, check it out. You may a $50,000 scholarship, a 10-day trip to the Galápagos Islands or a three-day site visit to CERN.
