This little film from Museum Sheffield should be on everyone's watch list right now. Unless you're already a fan of fossils you might not be tempted, but I found watching this collection of minerals and fossils change colour and glow under UV light completely mesmerising and super relaxing – and we could all do with a bit of relaxation right now. The effect is caused by impurities within the structure of the minerals, which I think proves the theory that imperfections are beautiful. So settle down for a couple of minutes and enjoy, turn the sound on too.
