Walking water is an odd phenomenon where water droplets are caught on a surface of water and do not coalesce with the larger body of liquid. This can is accomplished easily by vibrating the body of water so that there are standing waves on the surface. These waves catch the falling droplet and allows water to walk on water.
The whole video studies this phenomenon but my favorite part is the experiment done in space. The body of water is a hollow sphere placed onto a speaker. They tried all kinds of tones and music and observed different behaviors. It was the Bach cello music that caught everyone’s attention. See for yourself… The video should begin at 9:25

Second Place! The visualization of water bubble is so cool and amazing. I also like that the video is explaining why this phenomenon is happening.
1st Place. I was not familiar with the phenomenon of walking water. This is a great visualization of sound through a medium as well. I recommend watching the whole video for a better understanding.
1st place. How the droplets are being manipulated by science to behave inordinately by not going through the air gaps is quite interesting. How it seems like they’re just bouncing off a surface is a pretty rare sight for liquids. I like how the liquid phenomena almost depicts the liquid as a non liquid which is unique!
1st place! I’ve seen water droplets like this appear in soup or soda and I’ve always been curious about this – I’d be open to trying it for this class. Not only are there professional-looking visualizations, but also there are scientific explanations in the other parts of the video. I’ll remember the channel for further browsing. Good pick.
1st Place. This is a really unique experiment. I wish there was a way to zoom in on the small bubble/wall interactions and really visualize the physics better. The physical mechanism for ultrasonic cleaners might be similar regarding the collisions of bubbles with surfaces.
