On a clear sunny day the sky is blue, but why?

It is all to do with the nature of sunlight and how it interacts with Earth's atmosphere.

The sun's light appears to be white but is made up of all the colours of the rainbow, when the light travels through our atmosphere it is scattered in all directions by all the gases and particles in the air.

The blue light is scattered more than other colours because it travels in smaller and shorter waves, this is why the most prominent colour in the sky is blue.

This is "video painting" a form of interactive graffiti.

Art duo Blake Shaw and Bruno Levy developed the technique using electronic paint rollers embedded with infrared lights. The lights within the paint rollers send tracking information to a computer, which then tells the projector where to project video.

The pair wanted to "reimagine street art with the moving image" and have painted dozens of buildings and landmarks across Europe.

If you have metal fillings and you've accidently put tin foil in your mouth then you'll know it isn't a great feeling.

The reason it hurts is because you get a galvanic shock which is when your saliva makes an electrical current between the foil and your fillings.

So if you have metal in your mouth make sure you remove all foil from your food or you might get an unwelcome shock.
