I think that this slow motion video of a Chinese singing bowl is the best of the web. The bowl works by rubbing your hands on it in a rhythmic way. After watching this video, I convinced a friend’s family to show me their Chinese singing bowl. The slow motion camera captures the spraying dynamics of the water in a fantastically detailed manner, it is truly mystical. The water is sprayed above the surface, almost dancing to the tones the bowl makes. Watching this video makes me want to learn more about fluid motion. It’s not obvious to me what causes this—I think its either some cavitation effect from oscillating pressure of some sort of resonant frequency effect. This is original work from “The Slow Mo Guys” Youtube channel. They have some other nice fluids videos.

1st place – the video with the music creates an insanely pleasing atmosphere that I could look at all day. This video is absolutely beautiful and I wish to try something like this for an assignment
Third Place. I love the way that the light shimmers/reflects off of the individual drops. It was mesmerizing.
2nd Place. Water droplets looked so shiny and their movement was so consistent!
First Place. The shimmering qualities of the water droplets created using a Chinese singing bowl exhibit the overall fluid motion of water. At the beginning, one can notice the initial rippling wave effects taking hold, along with the gradual vertical ascent of every water droplet. As stated previously, it would be interesting in knowing the various other variables that are behind the specific fluid motion witnessed in the video.
2nd Place. I think the flow in this video is created by standing waves. When the resonance begins, the waves are created. As the water is accelerated upwards around the antinodes of the standing waves, there is some critical acceleration for which surface tension and gravity forces are overcome and a droplet is generated. It could be interesting to find out what variables drive the standing wave geometry and tune this experiment for some desirable flow geometry (i.e. varying bowl geometries, resonance frequencies or fluid viscosities).
