Forget everything you think you know about champagne pops! Popping the cork won’t get much spray on its own and it lasts one second. I always recommend popping the cork before you shake the bottle.
Immediately after you’ve popped the cork, cover the mouth of the bottle with your thumb. With the top of the bottle covered, give it a really good shake.
Next, you can start to move your thumb a little bit – think of it as if you were spraying someone with a garden hose! Keep shaking until the spray stops.
I’ll make sure to pose you before we start the champagne pop, but generally I recommend one person holds the bottle and the other person snuggles in beside them.
