Want to see how ridiculously hot this summer has been? Drive to Baker, California and read the temperature on the world's largest thermometer. The 134-foot tall gauge is housed near the gateway to Death Valley, where temperatures soared to 134 degrees in 1913. While it's an electronic sign rather than an actual thermometer, it's known as the biggest on the planet. Next time you're in the area, it might be fun to keep a frying pan and some eggs handy.
