Your Magic Water Flower is powered by scientific phenomenon called Capillary action. Thanks to Capillary action, paper absorbs water very rapidly. When the paper gets wet, it swells which causes the folded petals of your Magic Water Flower to open up.
So what does all this have to do with your Magic Water Flower? Paper is made of tiny wood fibres which are tightly interwoven providing amazing strength and a beautiful writing surface. Even in high quality paper, there are billions of tiny little gaps between the fibres.
When paper comes into contact with water, the amazing power of capillary action rapidly draws water into all these tiny spaces. It’s because the water is slightly more attracted to the wood fibres than to itself. This helps trees and plants to lift water from their roots up to their leaves.
