Where Does This Cloud Come From?  

I want you to record this with a phantom camera close up

The key to understanding this phenomenon lies in understanding what is actually happening when solid CO2 sublimes in liquid water. I imagine that if we could observe this process directly, it would be incredibly violent and tumultuous owing to the huge temperature difference between the two materials. I imagine that the flow of thermal energy into the solid CO2 from the water is not perfectly uniform across the interface. I imagine that the CO2 molecules are not breaking off of a perfect crystal lattice and one by one leaving the surface to either diffuse into the water or pile up and form a pure little CO2 bubble. Instead, I imagine that water molecules are interacting with the surface of the polycrystalline solid CO2 in some places more than others, causing a great deal of stress in the material and opening fractures in the grain boundaries and other defects. I imagine that relatively large chunks of solid CO2 are being launched away from the bulk of the material, being propelled by the pressure of gaseous molecules of CO2 which have just absorbed the energy required to sublime and are now bouncing back and forth inside of the fractures, which very quickly forces these chunks off into the vast abyss of liquid water. I imagine that these chunks continue to absorb a great deal of heat from the water, exploding into smaller and smaller pieces, until there is nothing left but CO2 gas. I imagine that other volumes of gas are being created nearby from other chunks and that these volumes, if they are close enough in space and time, will merge to form large bubbles. We know that the water has a fairly high surface tension and we are only under about 1 atmosphere of pressure, so very little of the CO2 will readily diffuse into the water, and bubbles will be formed. Now, remembering how I imagined these bubbles were initially created, we must not forget that there was water in the midst of that chain of explosions. The water that interacted with the solid bits of CO2 transferred thermal energy to the CO2, which cooled and slowed the water down, and at the same time made the CO2 go crazy. So the water in the midst of all those chaotic explosions of gas suddenly found itself blasted into pieces and surrounded by a volume of CO2 gas. These tiny pieces of water will quickly shape themselves into tiny spheres or droplets due to surface tension and become suspended in the volume of CO2 gas due to their small size. This volume of gas may now merge with another volume of gas to become a bubble large enough to carry the droplets up to the surface of the water to form your cloud.

Is there anyway I can contact you about an experiment you did in thr past about dry ice
