Have you ever poured a bottle of wine down the sink because there was something wrong with it? I've done it only twice that I remember, but the next time it comes up, I'm going to try this trick. I'm going to pour a glass of wine, grab a copper penny, clean it off, and throw it in the glass.

According to scientists, this will get rid of burnt rubber, rotten egg and burnt match smells, all caused by stinky sulfur molecules called thioles that can be produced during the fermentation process.

What the video doesn't explain is whether you need to use an all-copper penny or if a copper-plated penny will work. Pennies made before 1982 are made of 95 percent copper. Pennies made after that date are made of 97.5 percent zinc and are plated with a thin copper coating. The video says to grab an "old penny," but it doesn't specifically say to pull out one made before 1982.

I've thought about how to get the answer to that question too: pour two glasses and put an pre-1982 penny in one and a post-1982 penny in the other to see if it makes any difference.

Next time a bottle of wine spoils, I'm trying this
Instead of pouring an off-tasting bottle down the drain, I'll reach into the coin jar.
