Watching 15,000 dominoes fall in a triple spiral will make your day      

It's hard to look away when thousands of dominoes are falling over, and even harder when they are in a cool triple spiral like this.

Domino builder Hevesh5 spent 25 hours over eight days building the pattern with 15,000 dominoes. The entire structure takes less than two minutes to come down as the chain reaction works its way along three separate paths at three different heights.

The clip has been viewed almost 7 million times on YouTube.
