*What's life about*

Another fact.

Rainbows are a optical illusion caused by light refracting off water droplets in the sky, which is why most rainbows occur just after it has rained. Even though rainbows can be filmed/photographed, they do not have a "physical location" and they are always directly opposite the sun when you see one.

I knew about this
Did you know the earliest form of fibre optic cable came from an idea of light refracting through water?
In 1854, John Tyndall demonstrated to the Royal Society that light could be conducted through a curved stream of water, proving that a light signal could be bent.

I didn't actually know that, will be looking more into that mate

Virtually every aspect of science can be applied to water, physiques, chemistry, biology, environmental, medical, geology and so on. Just the amount of uses and what it can do is mind boggling. I mean it's amazing that water in it's liquid state can practically act like a mirror, though it can't "reflect" light.
