What causes double rainbows?
Posted on 18-10-2012 by Alex, question asked by Alfred
Now that we understand rainbows and how they are formed, we can go deeper into the science behind them, and explain the workings of something much more mysterious; the double rainbow. For ages it has been seen as a sign of good luck and something even more magical than a single rainbow. Mainly because it is even rarer than a single rainbow and much

How do rainbows work?
Posted on 18-10-2012 by Alex, question asked by SoobNauce
Rainbows are one of natures most beautiful and amazing sights, mystifying people since the dawn of time. Inspiring hundreds of stories, myths and fairytales, rainbows are a source of fascination to many, however they are not well understood.
So let us ask ourselves a few questions; How do rainbows work? Why always those colors? And why are they always arcs?

What is the color of the Sun?
Posted on 08-10-2012 by Alex, question asked by Jack Sulser
We all know the Sun as the big yellow disk in the sky, providing us with light and warmth. However if we look at the Sun at sunrise, sunset or even through a cloud, it suddenly turns red or orange and around noon it seems to be white. If we stop to think about it, then we realise that this is quite odd, what

Why are Planets Round?
Posted on 23-09-2012 by Alex, Anthon, question asked by Melvin
If we look at pictures of planets, stars or other celestial bodies, we soon see a resemblance between them: they are round.
Now one may wonder why this is so, why can't we have cubic or pyramid shaped planets?
To understand what is going on here, we need to first look at gravity and learn a few things about the creation of celestial bodies like the

Why do wet clothes get darker?
Posted on 15-09-2012 by Alex, question asked by Jim
We all have the almost instinctive ability to tell the difference between a wet and dry surface. Knowing that dark spots on clothes, blackboards, sand, roads and many other things usually indicate these to be wet spots. On top of that it also makes some materials more translucent, just think of a wet shirt.
The question that arises from all these observations is;
