Program 3 of the annual Royal Institution was shown on 30th December.
If you are curious to see a canon ball floating in mercury (thank god the HSE jobsworths didn't prevent this demo) and aerogel on 'display' (not much to see really). I expect it will be on the Iplayer for a few days - not that I use the iPlayer so I cannot advise in that respect.
There is some pink goo like a huge tongue in the background but I must have been distracted as to its purpose.
