If you have the willpower to open a bottle of wine and not finish it, you've probably been faced with the dilemma of what to do with half a bottle of opened, oxygen-spoiled wine.
Well, worry not, my fellow vino-loving friends, because we have the answer.
According to the scientific geniuses at Reactions, the only thing you need to revive a spoiled bottle of wine is one (very clean) penny.
Here's what you do: Drop the penny in your glass of wine, and stir it around with a metal spoon. The copper in the penny, according to Reactions, reacts with the sulfur in the wine to create copper sulfide. This intimidating-sounding chemical is actually what makes your beloved vino palatable and, you know, drinkable again.
Honestly, I don't entirely get it — and thinking about all the dirty hands that may or may not have touched the penny I'm supposed to dunk in my drink is a little horrifying.
But, in a pinch, it seems like a great trick. Waste not, want not, right?
