Are you sick and tired of having to get your grubby paws into egg yolks every freaking time you have to separate them? Well, luckily, we just stumbled upon this neat Japanese GIF , which shows you how to do it properly: How to separate egg yolks The logic behind this is that squeezing the bottle spits out air, then releasing it forces it to suck up air.

No more having to shove your hands in there , and probably also crushing the yolk in the process.
