I find this interesting from a flow visualization perspective, as the mixing of the two solutions is invisible until a chemical reaction takes place. This chemical reaction produces a particle “fluid tracker” in situ to visualize the fluid flow, while the silver nanoparticles likely alter the fluid dynamics as they are created. As the silver ions become elemental silver, the density of the silver nitrate solution drops precipitously at the interface between the two solutions. In contrast, the reacted ascorbic acid, known as dehydroascorbic acid, remains in solution, and thus the density of the ascorbic acid/dehydroascorbic acid solution should in theory change very little.

The music pairs well with the video.
Very interesting video, I thought this was smoke being pumped in at first glance. I also find the music very fitting to the content of the video.
Loved how the music related to the movement. The movement of light within the glass of the fluid is really beautiful. It is amazing how you can see the silver nitrate react with the acid to form silver particulate.
The jet between the interface and the chemical reaction that allows the particle tracers to visualize this reaction are extremely interesting
I love the stillness of the round-bottomed flask compared to the motion of the flow. Great explanation of the physics and chemistry as well! What was your lighting and background setup?
I like the use of a chemical reaction, it adds a whole new layer to the video beyond just the visualization of a flow.
Certainly a cool video and effect that your’re capturing, but I really can’t tell exactly what is happening, which makes it interesting to watch. It gives something of an other worldly feeling.
It looks like the fluid is in a bubble which is quite an interesting effect.
It reminds of something out of Disney movie with the music, like snow white when she ate the apple. Something seemingly so pure, turning dark.
This is a really interesting reaction that you captured very well!
I love how the liquid is contained in the sphere, it adds a really interesting and pleasing addition to this composition.
