This video shows liquid convection currents produced by submerging a hot cylinder into a tank of cold water. These currents begin when the density of the water being warmed near the surface of the cylinder decreases, making it positively buoyant and causing it to rise toward the surface.

So cool!! I’ve never seen this effect before and I think you did a good job documenting it. I also like the contrast of white and blue
This is super creative. I love how you chose to display the physics.
This setup is super creative, I like all the frames we can see as well as the different speeds of the process.
This is really cool (or hot I guess). I really like how you can see the flow accelerate as it goes up the side of the container.
I love the physics behind this flow of the dye. The movement up the vessel is fascinating and beautiful.
Very interesting reaction! It’s neat how the object and flow interact.
