We've been fortunate enough to publish a commentary in the highly-regarded journal Nature Chemistry, discussing how to measure the impact of our videos.
It's a rather inexact science, as you'll see in our paper.
And even better, the publishers have made the article freely available for the next month - so anyone can read it without a paid subscription (UPDATE: This free offer has now lapsed... sorry!)
Stuck in a hotel room on a Thursday night, I have uploaded and updated some captions on our videos.
To get captions working, use the button under the player (with the little triangle on it)
First here's the embedded playlist of videos with English captions - all 122 of them. Note these have been transcribed by people, not YouTube's erratic automatic caption system!
(Small arrows which appear at the left and right side of frame allow you to scroll through the captioned various films)
And here is the up-to-date playlist of captions in Portuguese courtesy of our friend in Brazil, Luis Brudna. Amazingly, he has done 149 videos for us... Each one painstakingly captioned with detailed timings for each caption to pop up on screen.
3. To sign when people send in autograph requests... yes, it happens!
We had nine people there: The Professor Martyn Poliakoff, Neil Barnes, Pete Licence, Debbie Kays, Steve Liddle, Sam Tang, Darren Walsh, Rob Stockman and myself.
Only John Moses couldn't make it.
It was the first time everyone from the project had been in one room together and it was quite a good laugh.
I will reveal some of the pics as soon as we have them.
Essentially we've made a perfume, with all members of the team adding ingredients (except Steve, who was away in London).
I should stress the video is just a bit of fun - it is certainly not a recipe we'd recommend for human use!
The ingredients of "Mendeleev's Dream" are as follows:
Vanillin - the smell of vanilla Mendeleev brand Vodka Citronellol - the smell of lemons Eugenol - smell of cloves Cinnamaldehyde - the smell of cinnamon Boron Trioxide - because Debbie loves Boron Chocolate (Theobromine) - to provide the feeling of love Hippodamine - a Ladybird Attractant Platinum - to add some bling and glamour Direct Red 23 - to give it a red Valentine's colour Technician Neil's "Ingredient X"
We've even done a bit of market research, as seen in this "bonus video" for Test Tube:
So Valentine's Day is nearly upon us and I think we've devised two videos to make for the occasion - one each for Periodic Table of Videos and Sixty Symbols.
If we can find time to make them this week....
Ahead of that, here are a couple of previous efforts.
First, last year's Valentine's video from Sixty Symbols:
And chocolate and roses from or chemistry project:
A video about every element on the periodic table... 118 of them. All the elements have been done, but we're updating the films with new stories and better demonstrations. Plus we do extra videos on molecules, road trips, chemistry news and other cool stuff. A collaboration with the University of Nottingham's School of Chemistry.
All about physics and astronomy, loosely based around the symbols used by scientists. We also post regular videos in response to viewer questions. A collaboration with the University of Nottingham's School of Physics and Astronomy.
This is a new project all about numbers, part of an exciting YouTube project to encourage more original content on its website. Stay tuned for videos throughout 2012.
As with Numberphile, this a part of YouTube's new program of original videos. Here we're looking at distant objects in space, starting with an attempt to make videos about the famous Messier Catalogue of objects. But also venturing into other areas of astronomy.
The project which started it all. It's essentially a look behind the scenes in the world of science. Not just the typical stuff you see on TV, but the real story of triumph and failure... warts and all!
It also features out-takes and extra footage from other projects, such as Periodic Table of Videos and Sixty Symbols.
This project involves going backstage at some of the UK's top science facilities. They're mainly places run by the Science and Technology Facilities Council. The stories include the secret life of lasers, particle accelerators and spacecraft construction.
This is a new video project, all about the science of food. Topics range from flavour to fast food - food security to crop technology. Another project in collaboration with the University of Nottingham.
A video about every book in the Bible, from Genesis to Revelation. Not religious, rather an academic look at the most famous collection of books in history. Includes plenty of footage shot "on location" in Israel. And a new series all about verses.
A look at the story and history of various words, explained by experts in modern language and culture. Many of the videos focus on words which have their origins in other languages but are now used in English.
Scientists discuss some of their professional heroes. The "favourites" range from some of the most famous names in science through to humble people you've probably not heard of. A collaboration with Nottingham Trent University.
Blog goes behind the scenes with video journalist Brady Haran.
Brady's working on various projects, including the successful Periodic Table of Videos, Sixty Symbols and Numberphile.
