Glowing Samples

July 4, 2008 — Leave a comment

I’ve not much to say about this other than that it is a very cool image. I took it on Wednesday during Cardiff University’s Dragonfly Day. As well as making our own spectrometers there was also an experiment to deduce the contents of several mystery cups. All were white or see-through liquids. Using just their sense of smell and a UV blacklight, participants had to figure out what was inside each cup.

Just so you know, the contents were:

  • A Suncream
  • B Washing Power (for clothes)
  • C Shampoo
  • D Toothpaste
  • E PVA Glue
  • F Lemon Juice
  • G Double Cream
  • H Tonic Water
  • I UV Sensitive Body Paint
