We're sorry to singlehandedly destroy all those Kodak moments of childhood birthday parties, family graduations, and wedding anniversaries - but you're not going to be able to look at any of them the same way after we lay this bombshell on you.

At all of these events, the person responsible for cutting the cake did it wrong. Every. Time.

It turns out that the classic, triangular-wedge method of cake-cutting we all know and love - and which seems, dare we say, so sensible, even intuitive - has actually resulted in the premature staleness of, and, hence, wasting of cake, in any household that lacks a member gluttonous and enough to eat any leftover cake, irrespective of approaching crispy-staleness.

Horrifying fact - and sadly, confirmed by science. Check out the video below from Numberphile to see how we should've been handling your cake-cutting responsibilities all these years. Go, and waste your delicious chocolate-infused cannabis cake no more.
