Really cool picture and idea. I really like the illustration of this flow that the video provides.
Great video. The music adds an amazing effect to the composition.
The flow is beautiful very interesting display almost alien
Really amazing to watch! The flow is beautiful.
Incredible! It looks like a surreal landscape with planes dropping red fire retardant.
The video was really nice, I wish you were able to use a tripod for some added camera stability. The phenomenon was imaged well. I think the salt composition may contribute to how the instability forms, but I am interested to see what you find.
Your video demonstrates a variety of fluid mechanics that are given a proper amount of framing, timing, and attention. Your choice of music characterizes the feeling of being underwater and is timed so well when the red fluid enters the scene. All the hues in this video complement each other nicely. Everything comes together to tell a visual and auditory narrative.
Beautiful. Excellent choice of music. Love the color choices you all made. You should utilize a tripod in the future to avoid camera shake so that there’s nothing to distract from the flow.
Cool video, very erie feel to it. The music add a lot of depth.
Wow. The music and the colors create a spooky sea scene. There is one point about halfway through where the focus is on the outside container and not the pour. Still so beautiful.
Really awesome work with the lighting.
The music highlights the otherworldly feeling of the flow. The flows themselves were spectacular. The video was pretty shaky, and I’m not sure if that’s what you were going for or not.
Great music and colors, almost an alien feel. I wish the footage was more stable, maybe next time use a tripod so the camera doesn’t shake so much.
This is so cool! It would be even cooler to see a time lapse of this.
