Here’s an experiment with nanostructures you can do in your (dusty) room

This is fantastic . In this TV , we see slow - movement TV of water droplets falling on a dusty surface . Because the dust is made up of a special metamaterial , the drops become locked into different shapes as they bounce .

Usually water form a global free fall , since its molecules draw in together via cohesiveness . When a droplet hits a surface , it will deform , but then it will essay to pull itself into that lovely sphere again . This sentence , scientist have cooked up a slight something dissimilar for the H2O by dropping them on aquaphobic gunpowder ( pulverisation that repels pee particle ) , which also forms nanostructures . So when different drops fall on the open , they become locked into the deformed bod they call for as they rebound off the surface .

We see them take shapes depending on their viscousness and whether or not they ejected a chip of body of water as they bounce . Some wrick into bowling peg shape , and some into icing emollient cones .
