A British math author found a way to slice cake so that it stays fresh much longer than usual.

The method is not new, it was developed about a century ago by the Victorian scientist Francis Galton, ABC News reported.

The researchers discovered fingerprints and even came up with the phrase "nature versus nurture," he also came up with the food preservation technique.

Alex Bellos, author of "The Grapes of Math," demonstrated the new technique in a Youtube video.

The researchers cut the cake all the way down the middle, removed a strip from the center; they then pushed the rest back together, sealing it up with rubber bands.

The cake-cutting method is supposed to keep the cake moist for additional days than if the "wedge approach" had been taken.

"[Galton] was the king of measurement, and he was very English. He loved tea and cake," Bellos said. "He's not a household name, but so many of the things he invented are things we take for granted in the modern world. In his old age he sent [scientific journal] 'Nature' this letter about the best way to cut a cake, and when I saw that, I thought, 'That is absolutely wonderful.'"

"We instinctively see the circle as a wheel, which is a point going around another fixed point, but if we stop and try to see it in a completely different way, then that's when you come up with this other solution," Bellos said. "It's also charming that it's something so simple invented by someone who was so important scientifically."

Bellos claims he has tried the method out several time himself and has seen results.

"It really works. It turns out that the strength of elastic bands is strong enough to keep it together, but not too strong that it [makes] too much of a mark or cuts through the icing," Bellos said. "Just be careful to make sure that you don't get a bit of rubber band in your mouth."
