The all-too-common debate: you really want that glass of wine, but the bottle has clearly gone bad. Instead of spending more money on a new bottle, you can save the spoiled wine for just a penny — with the penny itself, actually. According to the American Chemical Society, you should drop a penny (after thoroughly cleaning it, of course) into a glass of wine, stir it around, take it out, and voilà! Your bad wine should taste good.
This is all thanks to chemistry, of course. According to the informative video, the copper in the penny reacts to the thiol compounds (aka the stinky, sulfric smells of spoiled wine) and produces odorless copper sulfide crystals . . . who are we kidding, you don’t need to understand the science to appreciate this tip!
