Sir….. I would like to know whether it is possible to make the container …. if yes… what are the materials required?…. I was planning to do this experiment for the school science fair…

Thanks for the nice words. I agree… it’s a beautiful demo. There’s no science to the size of the tubes. Just make sure the gap between the two cylinders is about an inch or so. Again, it’s really a matter of trial and error. Just squeeze in the dye to make the dots and give it a try.

Let me know if it works for you. Love to see pictures or your video.

I enjoyed the demo. Would you provide some dimensions on the two cylinders? I guess it works better if the gap is small relative to the cylinder diameter, true?

When the color is injected, is each dot at the same distance from the axis of the cylinders?

Nice demonstration.

This is one great looking experiment! I’d love to try to recreate it at home, but that crank seems like it would be a difficult thing to replicate.

I think your experiment is awesome!
I am looking for ways to keep 3rd grade students on task during science class.
Any ideas?
Thanks.

That is an awesome effect with those dots! Why didn’t they do any of those experiments in my science class?! All I got was hydrogen going ‘bang’
