A domino enthusiast has broken his personal record and caused and internet sensation by balancing 60, 000 dominoes just to knock them down. I was a bit disappointed with this clip I felt it could have been a little bit more exciting. Each of the 60 big dominoes in the chain contained 990 dominoes, with 600 dominoes used to spell out numbers on the floor, making a total of 60,000. The task took YouTube user FlippyCat 65.5 hours to complete but took only 12 seconds for all the dominoes to fall down when pushed. The video has created a lot of internet interest with over 800,000 hits in just over a week.
