Can you unboil an egg?

In this article, we will answer the question “Can you unboil an egg?”’, and how to boil eggs?

Can you unboil an egg?

Yes, you can unboil an egg. Yes, you heard us right. A team of researchers led by Australian Academy of Science Fellow Professor Colin Raston invented the machine called Vortex Fluidic Device (VFD), that can not only unboil an egg but also do many more wonders. For example, the VFD can produce alternative fuels and medicines in a hassle-free way with satisfactory results. 

Moreover, it can cut the carbon nanotubes tiny pieces with a consistent size. The principle behind the working of the VFD is that it spins the liquids at extremely high speeds and precise angles.

How does the VFD machine unboil an egg?

Step 1: Boil your eggs

Before boiling, the proteins in the egg white or albumen of the egg are weakly bonded to each other, in a complex pattern or network. When you boil an egg, you are providing thermal energy to the protein strands to break through their weak bonds and form new and stronger bonds. 

The formation of new bonds restricts the motion of the protein and strands that turn the eggs whites into a solid, gel-like mass. 

Step 2: Add some water and urea

The next step is to cut the eggs whites as precisely as possible and mix them with urea. After the addition of urea, the egg mixture is no more edible. The urea and egg white mixture is further dissolved into water. 

The purpose is to digest or liquefy the egg proteins. At this point, you have mechanically cut the protein bonds but the chemical bonds still need to be broken.

Step 3: Spin the egg and urea mixture in the VFD

The egg mixture is spun at a speed of 5000 rotations per minute n the VFD. the spinning motion pushes all the liquid to get deposited on the sides of the glass tubes in a thin layer. 

The difference in velocity between the liquid closer to the wall and the liquid that is more centered induces shear stress on the protein strands. The protein bands are pulled and pushed until they recoil back into their original shape before boiling.

How to boil eggs?


  • 12 Eggs
  • Coldwater
  • Ice water
  • salt & pepper for garnish optional


  1. Fill a large saucepan with enough water to completely submerge all the eggs.
  1. Place the saucepan over high heat and bring the water to a rolling boil.
  1. Boil the eggs for 4-12 minutes, depending on what texture you prefer. Set a time to be accurate about the boiling time. This ensures that you don’t overcook or undercook your eggs.
  1. Remove the boiled eggs from the boiling water and transfer them to an ice bath. The temperature shock will immediately halt the cooking process. 
  1. When the eggs have cooled down, crack and peel them.
  1. To make sure that no cracked egg bits get stuck to the boiled egg, dump the peeled egg in cold water.
  1. Slice or cut the boiled eggs into the desired shape and size. Season with salt and pepper and enjoy.


  1. Never dump the eggs in already boiling water. This prevents the eggs from cooking evenly. Place the eggs in cold water and then heat until the eggs are boiled.
  1. Shocking the eggs by transferring them from boiling water to an ice bath loosens the eggshell from the egg and makes the peeling easier.
  1. The presence of a green ring around the egg yolk is an indication of overcooking.

Perfect hard-boiled recipe


  • Eggs 
  • Water 


Method 1: Rolling boil

Fill a saucepan with 2 to 4 quarts of water and bring it to a boil. Dump the eggs into the boiling water and reduce the heat. Large eggs boil for 14 minutes, medium and small eggs for 12 minutes, and jumbo eggs for about 15 minutes.

Dump the boiled eggs in a bowl of cold water to halt the cooking process.

Method 2: Quick boil and let sit

Fill a saucepan with cold water and then add the eggs. Cover the saucepan and bring the water to a boil.

Turn off the heat and let the eggs sit in the saucepan with the lid for about 15 minutes (12 for medium and small, and 18 for jumbo).
