## Why It Works
Squeezing the bottle expels air. When you place the opening against the yolk and release your grip, the bottle tries to return to its original shape, creating lower pressure inside than outside. That pressure differential is enough to lift the yolk cleanly off the white, because the yolk's membrane is intact and acts as a single unit under suction. The white, being liquid, flows around the opening and stays in the bowl.
## How to Do It
1. Crack all your eggs into a wide, shallow bowl. This gives you room to maneuver.
2. Take a clean, empty plastic water bottle (16 oz works well — bigger bottles create too much suction and can break the yolk).
3. Squeeze the bottle about halfway, compressing the sides.
4. With the bottle still squeezed, place the opening directly over a yolk.
5. Slowly release your grip. The yolk lifts into the bottle.
6. Transfer the yolk to a separate bowl by squeezing gently over it.
7. Repeat for each yolk.
## Pro Tips
- The bottle opening should touch the yolk, not hover above it. Contact makes the seal that allows suction to work.
- If your yolk breaks, it happened before the bottle — a broken yolk won't transfer cleanly regardless of technique. Crack more carefully next time.
- Cold eggs have firmer yolks and work better with this method. Separate straight from the fridge.
## When to Use This
Ideal when separating more than four or five eggs at a time, when your hands are already messy, or when baking and you don't want any trace of grease on the whites from your fingers. Also great when someone else is watching and you want to look like you know exactly what you're doing.
