More on what water can do to light.
Remember my fascination with dandelions? Just to remind you:
Especially in combination with coins and water droplets, dandelions are a source of nearly endless entertainment:
See how much cooler 1 NOK coins become only by adding a little water?
Here the same two coins in the sun – see how the water droplet in the coin in the back focusses the light whereas the empty hole in the coin in the front is just a hole?
Pretty cool stuff. And in the next post I’ll show you what this very effect does out in the real world!
