The Internet gifted us countless food hacks this year, from hulling strawberries with a straw to juicing lemons without getting your hands sticky (or a single seed in the bowl). But this newly viral cake cutting hack is arguably the most genius of them all…or the most horrifying. Instead of using a knife, the hack suggests using wine glasses.

Here’s how it works. Once the candles are blown out and removed (P.S., you might want to look into buying a cake shield before blowing your germs all over your next birthday cake…just sayin’), every guest simply takes their wine glass, pushes it through the cake and scoops a “slice” for themselves. No knife necessary.
