Sabrage, the process of opening a bottle of champagne with a saber, is a fun ceremonial tradition that's great for impressing party guests. You don't necessarily need a saber for this party trick, however.
This video, from the Wine Folly YouTube channel, shows that you don't even need a knife to dramatically pop open a bottle of bubbly. Put on some protective eye-wear before you do anything, and be sure to clear the area around you. Chill your champagne so the bottle is extra cold. Then remove the foil and cage from the cork, grab a sturdy spoon (or fork or butter knife), hold the bottle at a 30 or 45 degree angle, and quickly slide the spoon up the neck of the bottle.
Now you're ready to party like its 1999 by pouring it all into a super classy champagne tower.
