Ah, beer. If you're smart enough to keep a bottle opener in your kitchen, gluing a magnet to it can help keep the bottle caps from flying all over the place.

Redditor therealslimjim05 shared this tip to keep bottle caps from littering the place: just glue a strong magnet to your bottle opener. When you pop the cap off, it'll stick to the bottle opener, saving you from losing it down the drain, flinging it into someone's eye, or stepping on it in your hung-over haze the next day.
