Cadbury’s Creme Egg…

There is a great channel on YouTube called the Periodic Table of Videos. They are led by the crazy-haired chemistry professor Sir Martyn Poliakoff at Nottingham University. They started out attempting to make a video about every element on the Periodic Table. They have since branched out into all manner of delightful demonstrations. Inspired by recent Creme Egg crime stories in the news I thought of this old Easter Special concentrating on various ways to mistreat a Cadbury’s Creme Egg.

Poor Neil! I often wish I had a lab technician.
