A recent video uploaded to YouTube shows Japan's superfast Maglev train on a test run. The train, which essentially "floats" on a series of magnets, limiting friction, allowing trains to travel at speeds of up to 311 mph. With the train, trips from Tokyo to Nagoya would take about 40 minutes.

Check out the video below of the train in action -- just don't blink, or you might miss it!
