What water can do to light.

In the last post, I showed you a couple of pictures of a vase filled with dandelions.

Dandelions and light being focussed by the water in the vase.

Turns out this might not have been enough of a clue, so here we go:

Isn’t it amazing time and time again how water refracts light and makes things look distorted?

Refraction of light in water.

This can be used for all kinds of cool experiments, provided you have the right kind of coins at hand:

1 NOK with a water droplet in the middle, acting as a lens. See how the dandelions are flipped upside down in the middle of the coin?

This kind of stuff keeps me entertained for quite some time!
