Are you looking for an ingenious way to recycle your burnt-out light bulbs? You could transform them into tiny terrariums, repurpose them as flower vases, or even decorate them to be used as holiday ornaments. If you are more interested in practical applications, however, you can always use light bulbs to brew your morning coffee. YouTuber The Q has designed a one-cup coffee maker constructed from light bulbs that not only serves as a conversation piece but also demonstrates the importance of physics in everyday life.
According to YouTuber The Q: "A vacuum coffee maker operates as a siphon, where heating and cooling the lower light bulb changes the vapor pressure of water inside it. Water is pushed up (or pushed down) the siphon tube into (out of) the upper light bulb."
