I love this one; it is so interesting to watch. I love watching the jacket distort under the droplet. The drop that comes off at the top gives a sort of optical illusion. It looks like it’s going to hit the other one on the jacket, but it’s actually behind it. Weird.
Nice video of an everyday event which we can’t fully appreciate with the naked eye. I enjoy watching the process repeat itself with the little droplet. Focus and lighting are very good.
Very cool effect. I am curious to know how much the jacket has gotten. The surface seems very water resistant and hydrophobic.
1. The video is fantastically artistic.
2. The fluid physics are well shown.
3. The video technique is great.
Awesome video, the crisp and sharp focus really makes video. Music is so peaceful, little droplet that gets pinched off of jet is so cute.
Very crisp and good field of view. I like the bottom droplet seemingly throbbing after it spreads and comes back together.
The is an interesting view of the hydrophobic dynamic interaction between the droplet and the surface. It is almost a bounce but the droplet just barely stuck the surface, which seems to result in the jet instead of a complete bouncing droplet. The second droplet, formed from the jet, may actually bounce behind the first drop. It is hard to tell though
Super cool to see the drop spread and suck back together to create the jet off of the surface. interesting to see the split and the motion of the flow.
Great focus and detail. I like color choice of the background. The lighting is great. Awesome capture of the fluid flow.
Great music choice, and a nice field of view. I would be interested in having the video cut to a more zoomed in field of view at the end.
Great capture of this interaction between a water droplet and hydrophobic surface. The slow motion really brings out the details of what is happening in the interaction.
Nice video! I like the focus, the lighting, the speed, etc. Good audio choice!
Good focus and field of view. It was interesting seeing the droplet form its own Worthington jet.
I think you could have zoomed in towards the droplet as there is a ton of negative space and you could better show the flow.
The peaceful music really goes well with the video. i like the visual effects of the fluid flow. A worthington jet effect using hydrophobic material.
Dope ! I love the reaction. The background and focus is great
Very abrupt ending but super cool video! The red is a cool color to drop it on and seeing what is actually happening is amazing! Such a good focus the edges are incredibly crisp!
Well lit, well focused video. Possibly consider cropping out some of the bent fabric in the top right of the video. Very cool Worthington jet on a solid surface.
Fantastic job with the focus and capturing this phenomenon, the initial ring is spectacular.
Super interesting how far out the droplet spreads before coming back together! Nice lighting and super crisp focus also
