Cadbury Creme Eggs

This video was a last-minute decision, and I'm surprised how well it turned out.

For our "Easter Special" on the Periodic Table of Videos, I suggested we do some experiments on Cadbury Creme Eggs.

I had visions of a series of tests on the eggs' physical properties.... boiling points, density, strength, etc.

Sam Tang and Neil Barnes came up with a better idea, putting eggs into a vacuum (the equivalent of outer space) with fascinating results.

Pete Licence then popped in and dropped an egg into potassium chlorate, again with spectacular results. He had no idea what would happen, and you can see the reaction didn't kick off until he prodded the egg and released the sugar-filled centre!

I then asked Darren Walsh - who was lurking about to watch the action - if he'd pop an egg into liquid nitrogen and smash it (a chance to use the new slow motion camera, of course!)

Love Darren's reaction to the smashed egg!

It was the a mad rush home to have it all edited in time for the Easter audience.

The running joke about Neil being left with a mess to clean was not planned... It just worked out that way.

Neil's always bit of mysterious figure in our chemistry videos but absolutely crucial to making many of them. His role in this film has been attracted plenty of comments on the YouTube video.
