Drops on Drops on Drops
Typically, when a droplet of water plunges into a pool of water, it will bounce slightly and then coalesce with the rest of the water. But there's a way to keep the bounce going indefinitely.
If you put the pool of water on top of a loud speaker, you can vibrate the surface. This vibration can cause water droplets to continuously bounce and levitate atop the liquid surface.
Physicists Pablo Cabrera-Garcia and Roberto Zenit from National Autonomous University of Mexico conducted the experiments and filmed them with a high-speed camera for your viewing pleasure. Check it out!
You can learn more about the videos from the researchers' arXiv article. Also, check out the Division of Fluid Dynamics website for more videos and images. This year's galleries should be up in the next month or so.
