Did that opened bottle wine spoil a little quicker than you expected? With this chemistry trick you can undo the nasty smell and taste so you can finish off that nice red.
This video from the Reactions YouTube channel explains a simple way to try and undo the spoiling of your already-opened wine. Grab a coin (a 5c, 10c, 20c or 50c piece in Australia, and the cleanest looking one you can find), give it a good wash with soap and water, then toss it in your glass of smelly wine. After you give it a few stirs, the coin will counteract the stinky thiols in your wine. Remove the coin and your drink should smell and taste almost as good as new. Of course, you can do the same thing with a silver spoon if you happen to have one around, and it's probably preferable to sticking coins in your glass. All in all, you're better off properly storing your opened wine so it lasts longer, or even trying to return it to the store if the spoiling wasn't your doing, but this will do the trick if you're in a pinch.
Keep in mind, this trick may not work on every bottle of spoiled wine out there. Wine can spoil in different ways, meaning this will work sometimes, but not all the time. You'll always be better off not letting your wine spoil in the first place. Still, if it has spoiled, this trick is worth a shot as a last ditch effort. You can learn more over at Gizmodo.
