What’s more impressive than opening a bottle of bubbly with a long ceremonial saber? How about sabering a bottle of Champagne with nothing more than the iPhone in your pocket.
A new video by Business Insider breaks down the process into four simple steps: Find the seam of the bottle. Hold the bottle at a 45-degree angle. Take some practice swipes with the iPhone. Then strike firmly and all the way through the neck to remove the Champagne bottle’s cap, collar and all.
The trick seems to work best with flat-edged devices like the iPhone 5. And of course you could injure your phone (or yourself), so dazzle friends at your own risk.
