Check Out What Happens When a Water Droplet is Pierced by a Needle

Here ’s a smooth kinetics video that shows us a water droplet falling onto a hydrophobic phonograph needle . It ’s pretty nerveless ! Instead of spread out into a puddle , the drop turn into a empty cap of moving water supply .

Here we see a conflict between a droplet of piddle , full of molecules that attract each other , and a hydrophobic needle , which is driven into the heart of the droplet and attempts to motor the molecules asunder . The TV gets particularly nerveless around the 1:46 patsy , where we see , simultaneously , the path a droplet behaves when it rack up the flat land , and the fashion a droplet behaves when speared by the needle . I ca n’t decide which I like better , when the drib stays together as a ring , or when the drib give way up into wildly wing smaller droplet . You ?
