OK this is rather lovely – I spotted Alom tweeting about this earlier but have only just sat down to enjoy it with full attention. He’s showing a demo of the ‘iodine clock’ and how it might be used at different key stages to demonstrate different aspects of reactions. But also just for the sheer enjoyment of having a bit of science happening right in front of you 🙂
Readers may remember StoryCog who produced what I think is the best and most entertaining job description I’ve ever seen (and I’ve seen several hundred): http://storycog.com/files/StoryCog_Job_Description_2010-01.pdf – they are the people behind ScienceDemo.
I do recommend visiting the video’s page on ScienceDemo’s site to see Alom’s comments about the video as well as those from other science communicators.
