There’s a lot of interesting physics in this video. I particularly like how the water droplets exploding from the surface reflect so much light, giving the impression of glitter. The ripping open of the balloon could be slowed down a bit to see some more details, but perhaps that was not your intent for the video.
Art: The contrast between the background and the balloon is great, the slow motion speed for this video was quite appropriate.
Flow: The flow is quickly understandable and recognized.
Photographic technique: The focus was good, but the lighting could be a bit better to really highlight the water droplets.
Very cool to see how a seam forms and is pulled open around the water. The fine spray pulled off the surface of the body of the water reveals the high shear there. It looks to me like the membrane of the balloon strikes the corner between the air bubble and the water which creates the jets of water you see on the top. Good lighting and focus.
That’s cool! It reminds me of an image that captured the moment when a soap bubble popped. And the post-processing is very good too. Completely removes distractions.
Beautiful video. Music would be nice. The droplets are cool and bright.
Really awesome video! It is very neat to see this phenomena slowed down to a whole other level that shows what is really happening when a balloon is popped.
very neat to watch. The dynamics of the surface originally in the air bubble in the balloon are intriguing. Nice focus and lighting
This really shows the interaction of the boundary of the balloon and the water. The friction is really shown well and is really cool
Love how the droplets are acting as sparkly prisms. It’s fascinating to see how the water is moving up into the space where the air bubble was. Great lighting and focus. Love how you can see the water begin to engulf the needle.
1. Neat concept of popping the balloon on an air pocket. The slow motion video is very artistic.
2. The fluid physics are well shown.
3. The video has great focus and the speed is just right.
Popping on the air bubble is very interesting however I did not realize that what was happening because the video starts to abruptly I think. I would try and show a couple seconds before the pop. Always nice to see the shearing force of the balloon on the enclosed water.
I love the shimmer effect that the water droplets create. It’s interesting to see the water climb up the nail. A little bit more lead in time up to the pop would be nice.
The visual your team captured are amazing. The level of detail gained from the super slow-motion really helps to understand the fluid dynamics. Adding a voice over or some kind of sound would be nice, in my opinion. Also adding a few seconds to the beginning of the video would be useful because it allows the viewer to understand the context of your video before all the action has occurred.
Nice video! Interesting phenomenon where that jet seems to form where the balloon is broken initially. The color and focus is really nice.
really cool to see how the water splits into little droplets along the seam of where the balloon is popping. Interesting jet motion that you have at the point of rupture for the balloon.
Very cool video. Focus is good, framing is nice. Always cool to see things like this in super slomo. $150000 cameras work pretty nice.
Amazing fluid flow! This water balloon explosion is different than the other ones and the flow can be clearly seen. I like how the water particles glistens and sprays out uniquely.
Really interesting phenomenon, you did an incredible job focusing on the ballon and a good job with the analysis of the flow.
I like what you did in the post processing. Makes the water sparkle more. Always cool to see slow motion videos that captures the flow in greater detail. Great video quality.
The thing that really struck me with your video is how long the water stays in its shape and color. Looks exactly like red jello to me. Good lighting and focus also.
