Inside a tornado

Have you ever seen the movie Twister. There are some tornado chasers who try to put some recording instruments within a tornado. These guys actually did it but without the ping pong balls. There are some pretty impressive videos of a tornado from a short, squat cone that had 6 operational video cameras. The last part of the video shows the how the path of the tornado goes through some corn fields and barely misses a farm house. Wow!
