As our lives evolve from analog to digital, many of us are left with relics from our pencil-and-paper pasts. One such albatross is the filing cabinet. What can you do with a filing cabinet in a paperless world? If you're ingenious like YouTuber Catfish and Carp, you upcycle your vertical metal file cabinet into a homemade smoker. With a capacity of 25 lbs. of salmon, two racks of pork ribs, and 12 chicken drumsticks, the file-cabinet smoker has enough space and power to feed all the guests at your next block party.
