Things can get pretty tense when you're splitting a pizza between friends. After all, everyone wants their fair share.
In most circumstances, people opt to cut their pizza into segments using straight lines that cross in the middle.
But according to two mathematicians from The University of Liverpool, it's not actually possible to equally divide the slices this way.
To stop any pizza wars from being declared, the academics investigated ways to slice a pizza more fairly.
They found that the key to creating even slices is to cut them in curvy lines instead.
You can then add even more lines if more friends come over to create a stain-glass window effect.
You'll never fight over slices again.
