You really can separate an egg yolk from the white using just a plastic bottle. We didn't believe it either until we gave it a crack (excuse the egg pun) - and were blown away by how easy it really is.
This handy hack is quick, easy, and really works. All you need is a medium-sized plastic bottle - and a couple of cracked eggs that need separating.
Hover the bottle over the top of the egg yolk, squeeze the bottle with your hand gently and watch as the yolk gets sucked up into the bottle as you release your grip - it really is that simple.
The quicker you are, the better. We learned that you can only keep the egg yolk in the nozzle of the bottle for a few seconds so make a swift movement when separating the yolk from the white for success every time.
TOP TIP: Don't press the bottle down too firmly on the egg yolk otherwise the yolk will crack and you won't be able to suck it up and remove it from the white. Be gentle but firm with your technique and you'll have success in no time.
