When British puzzlemaker Tony Fisher made his Guiness Record-setting World’s Largest Rubik’s Cube, he almost seemed underwhelmed by his own finished project. "I am sure some people will ask why I have made this cube, and what's the point," he asked in a YouTube video, as he calmly pushed the 220-pound puzzle out of his garage and into his back garden.

One could ask the same thing about why he made a working Rubik’s cube out of Cheddar cheese squares, but we kind of know the answer to that question: because he is clearly some kind of lactose-tolerant genius.

“This one is pretty crap,” Fisher admits, again downplaying his own wizardry. But it is a little crap, especially when compared to some of his other creations, like the Rubik’s cubes he’s made from ice or from lit candles—or that record-setting, garage-sized monster puzzle. But the cheese cube does work, and he uses different colors of pushpins as stand-ins for the colored squares on a traditional Cube. In a second cheese-related video, he shows how to solve the cheese cube, “using a method that [he] devised in 1980.”

Fisher’s ingredient of choice was a block of Sainsbury’s Full Flavour Cheddar Cheese, which he cut into squares and attached to a plastic Rubik’s base. There’s something oddly soothing about watching him twist several giant hunks of cheese, holding it above a TV tray as he sits in his sparsely furnished living room. (It is less soothing to watch him eat it, after he’s handled it for several straight minutes).
