Hands up if you always cut a round cake using the triangular slice method? Well, here's a bit of life-changing information (or at the very least a handy tip for your next birthday cake).
The triangular slice is not the 'scientific' way to cut a cake. Instead, writer and mathematician Alex Bellos recommends a different approach, which also helps keep any leftovers fresher longer. He cites a Letter to the Editor from Nature, a weekly science magazine, that dates back to December 1906.
Following the century-old notes and illustrations, Bellos cuts a round cake down the middle and removes one long rectangular piece at a time, allowing the two halves, and then four quarters, to be pushed back together again. Check out his short video and prepare to be amazed!
