This video displays the head on collision between two vortex rings or toroidal vortex. Different dyes were used as well as a Phantom V2511 which is capable of very high frames per second to capture ultra slow motion. The formation of these vortex rings occur when the compact mass of a fast moving collides with the fluid in the opposite direction. Due to the friction at the interface of the two fluids the outer later flows down relative to the core creating the vorticies. A interesting phenomenon is as the vortex ring disperses, there are smaller vortex rings which emanate perpendicular to the original. The combination of colors and complex shapes produced in this experiment provide a beautiful and peaceful video.

    Second prize for best of web. The two vortex rings colliding, smoothly spreading out, then breaking off into smaller vortices is incredibly interesting to watch. The choice of colors used in the fluids also make this interaction very beautiful.

  • This is my vote for 2nd best of web. The aesthetics are interesting. The beauty of fluid dynamics is captured, but so is the beauty of the experimental set up. Cohesive and adhesive forces are also displayed.

    Third Prize
    This is a very beautiful fluid interaction. The intricate ways that the two flow colors combine after impact always looks great. The flow is always very smooth and it is great that the dye does not mix well with the fluid in the tank. It is also crazy that it took them 3 years to make the system that could produce this specific flow.

    Third prize for BOW. As Megan stated, I really applaud the setup of this experiment and what had to go behind capturing these images. The secondary vortex rings that incorporate both dyes are beautiful. I love watching Smarter Every Day, thanks for sharing!

    3rd place best of web. The scientific setup of this experiment is clearly advanced. The resolution of the cameras that were used is also amazing. I really like the use of color in this video. Not only does it look vibrant and beautiful, but the interaction of the two fluids is very clear. The viewer can see the motion of each colored fluid as it interacts with the other. I also like the small segments that form along the diameter as the fluid breaks apart.
