I took Raffy and Monty to the Kent Festival of Science on Wednesday, which is held at the Simon Langton school in Canterbury, about this time every year. The boys had a great time trying out various cool things and collecting badges - there is far more going on than you could possibly see in one visit, so we'll be coming back next year.

In this shot, Raffy is taking part in a Forensic Science demonstration and is holding a test tube of bright yellow lead iodide...
