What happens when you open a bottle of champagne and you don't finish it? Of course you put it in the fridge, but then it's going to go flat.

I saw a life hack this morning on the Today Show and my jaw hit the floor.

If you have a bottle of champagne that has gone flat, drop a raisin in to it. Carbon dioxide is what gives Champagne its wonderful bubbles. Once the raisin is dropped in, the remaining carbon dioxide will adhere to its ridges, then release themselves back into the Champagne as bubbles. And that's when the fizz should get restored!

Also, if you put the bottle in the fridge, put the handle of a spoon in it. That will keep the fizz in the bubbly.
