Watch Water Freeze
Spray water onto the glass surface, then watch as it freezes in front of your eyes. Sounds no better than watching paint dry? You'd be surprised… Watched through the special polarising filters, the process of water freezing becomes an incredible rainbow of colours and patterns.
As the water crystallises into a solid, fabulous feathery patterns appear. These are different every time, so once you've watched your water freeze why not melt it with some warm water, then start all over again?
