Beautiful collision of two colored smoke rings

A red smoke ring and a blue smoke ring collide, with spectacular results. (Via Forgetomori)


    1. Yeah, well I bet this wasn’t the only time in history someone carried out this particular experiment. There have to be higher resolution videos of this phenomenon somewhere.

  1. SCIENCE! Making the most boring topics look fun and extremely cool (since the invention of the scientific method?)

  2. How pretty! The resulting wave pattern from the collision are so interesting. It makes me want to replicate the experiment to see different collision patterns. Too bad my mad science lair is still in it’s dreaming of phase.

  3. Huh. I read the description as …”with specular results…”, which actually made it much more interesting!

    Awesome video, now I need more, too!

  4. Someone must know how this could be replicated with a computer model. That person should see this and replicate it. Then, said person should share the results here.

      Actually, for all intents and purposes air is, in fact, a liquid. Although I agree it looks like liquids, doing this experiment with smoke and then perhaps slowing it down should look the same.

  5. sweet! buddhists are saying “look its a mandala!”

    smokers challenge: replicate this by blowing colored smoke rings at each other.

  6. Yesterday I watched a jet’s contrails turn into pairs of rings. I’d never seen that before, and it was very , very cool. I tried to film it on my Flip, but I think it was too far away. Time to go check!

  7. The source link is broken.

    This is pretty frickin cool, as other commentators have said, I wish it was a higher resolution. I’d love for a screencap of it to be my background.

  8. This is in water. Dye injection study.

    Regular food coloring, two very simple jets, and a fish tank.

    I did my thesis on Vortex Ring Entrainment. This video brought back horrible memories of many Saturday nights spent in the bowels of a fluids lab, collecting PIV data. . .

    Relatively true although wouldn’t the viscosity differences between the clear/dyed water, and the smoke/air have to be identical to produce the same effect?

  10. I tried that through my red/blue 3D glasses. Alas, there’s too much red in the blue and blue in the red, or something.

  11. Hey guys! Wow what an amazing video! Now please anybody who understands the physics of this please explain this!… In my head when i saw this i imagined the awesome good old cliche of two dragonball z foes fighting in an epic battle and throwing opposing enegry balls at each other.. In the resulting collision either one beam would be destroyed or there would be a huge exposlion in the middle… Now in this smoke ring ring video when the rings collide it appears after the “explosion?” that most of the smoke on the edge is blue and the inner red.. What would this indicate? Using the dragonball z metaphor was the blue smoke more powerful? What was this because of? Larger quantities of smoke? Answers please!!
