Wow! We're going to make a cloud indoors.

Have you ever wondered what a cloud feels like? They may look light and fluffy but they're not. Clouds are made of water droplets and ice crystals. This makes them so heavy they can weigh more than an aeroplane. Check out our nitrogen cloud and watch as a cloud appears indoors before your very eyes. You'll also find out more about the three types of clouds. How wow is that?

So what is WOW! Science?

Don't try this at school. Get set to hear 'ooh's', 'ah's' and 'wow's' as our Inspirers bring you the experiments that are too dangerous or too messy to try in school. Harness the power of science to support your classroom learning. Boom!
