Then, maybe you head down to the beach to check out the sand castles and sunbathers, and your futuristic handheld interactive map tells you that there’s an awesome coral reef just a few yards out into the water. But you can’t very well just wade into the water with your pocket computer. It would get ruined! How are you supposed to see the sea turtles and gaze at the brain coral? Looks like Google Maps has lead you down a dead end street."
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
