There are words we often hear in the news or even use ourselves but cannot visualize. We just have a very vague idea of what the objects they stand for look like.

The Buzz Life decided to give some clarity to these mysterious things.

8. Black box

Paradoxically, a black box nowadays is usually an orange sphere. There are several versions as to why it got its name:

  • The first flight recorders were black and rectangular.

 

  • Because of their mystique: their contents remain secret for almost everyone.

 

  • The first recorders used to get covered in black soot after a plane crashed.

 

7. DNA

Everyone is aware of what the famous DNA spiral looks like. But few people know that it can be seen with the naked eye due to the length of the molecule.

To do that, you need to prepare a certain solution (you can do it at home — see the instructions here). The DNA will turn into threadlike strands that can be wound around a skewer or dried into a fibrous substance like the one in the photo.

 

6. Mastodon
