YouTube EDU on a Hair

We were lucky enough to have Angela from YouTube EDU come to visit on Monday.

She was joined by elusive YouTuber CGPGrey - here we're photographed at Nottingham's Robin Hood Statue.

Most of the day was spent at the University of Nottingham, where periodicvideos and sixtysymbols are filmed.

With Professor Martyn Poliakoff

We were also hosted by Dr Mike Fay at the Nottingham Nanoscience and Nanotechnology Centre.

There Mike was able to engrave the YouTube EDU logo onto a few hairs, including one of Angela's!

The logo was etched with a beam of gallium ions

Invisible to the human eye - but we promise it's there!

A tiny advertisement

They say imitation is the highest form of flattery....

You may recall late last year we made two videos about very small writing.

In one of them, we etched the world's smallest periodic table onto a human hair.

(and not just any hair - it was one of Professor Poliakoff's frizzy strands!)



Well after that, a big advertising agency got in touch with us.

Seems we had inspired them to write an advertisement on a whisker!?

And they even came over from France to make it on the very same electron microscope we used for our periodic table.

Here's their video about the making of the ad.
