It may sound absurd, but it is practically and scientifically possible to unboil an egg. A video by TED-Ed explains the process.

So while thermal energy can boil eggs, mechanical energy can undo the boiling. This is how it happens. Eggs are mostly made up of water and proteins. Proteins are held together by weak intricate bonds. Adding heat disrupts those bonds. The proteins unfold and refold into a more tangled form. This process is called denaturing.

So how do you unboil eggs? Adding more heat will tangle the protein further. Interestingly, spinning them around ridiculously fast can undo the boiling process.

Scientists dissolve boiled egg in water with a chemical called urea, a small molecule that acts as a lubricant, making it easier for protein strands to glide past each other. When we spin that solution in a glass tube at a breakneck speed, the solution near the tube wall moves faster than the solution in the middle. The difference in the velocity creates sheer stressants that stretch and contract proteins and eventually they snap back in their native states.

Thus the process of unboiling an egg is complete. Isn’t it cool. Watch the video for step-by-step process:
