How to tell if an egg is hard-boiled or raw

Do you know how to differentiate a hard-boiled egg from a raw egg? Watch the fascinating demonstration below:

There are 3 simple steps to test your egg:

  • Spin the egg
  • Stop the egg
  • Watch the egg

A hard-boiled egg will stop spinning after you stop it. A raw egg continues to spin even after you stop it. That’s because the egg yolk inside the raw egg is still spinning and swirling inside the raw egg’s shell.

Videography back story

So I recorded the actual demonstration a day earlier than the face-to-face video. I had to make sure the experiment worked first. Hey, I had to boil 2 eggs! The stove and I aren’t exactly close friends. Huh, why 2 eggs? Well, 1 egg was for backup, in case the original hard-boiled egg didn’t work out.

This meant I had 3 eggs to eat. Wait, where did the 3rd egg come from? Well, I scrambled the raw egg contents into some noodles. No food wasting, ok? So 2 hard-boiled eggs, and 1 scrambled egg with noodles. I do not want to see another egg in the immediate future…

That actual demonstration video was recorded on my digital camera, which is a little dated according to current standards. I can only get a 640 by 480 resolution, which is a far cry from the 1280 by 720 HD resolution I needed. Buuut, you use what you can get…

Snakes and eggs

Snakes and eggs

This is an excerpt from the latest issue of Singularity:

Most species of snakes are oviparous, meaning they lay eggs and their young hatch from the eggs. Oviparous comes from ovi, meaning “egg”, and parous, meaning “birth” or “having offspring”.

I researched on the topic because a colleague said all snakes lay eggs. Out of curiosity, I looked up information on various snakes and found there were 3 categories: oviparous, viviparous, and ovoviviparous.
