I visited the Science Museum in Minneapolis with some students recently. They have a large one, the kids were fascinated! It used a fogger on the bottom (maybe top, too). Four pipes with air holes angled inward (same effect as your slots) ran the full height. What was cool is visitors can reach into the vortex and disrupt it, they are relatively fragile things! I came here looking for ideas to try in the classroom, thanks for the ideas!

My daughter wanted to do the same thing about 30 years ago for a school science project. She made it out of scrap wood and plexiglass that I had hanging around. I did the power tool work, she did the rest. She got a ribbon for it. Her's wasn't a tornado, but a hurricane. Same principle.

just use a ultrasonic mist fogger. then you won't need boiling water or dry ice. you can buy then off amazon.

I actually tried them, but just couldn't make it work. I only had one fogger, so fog production was limited. I suspected that if I could reduce the updraft to the perfect "updraft / mist" balance, it would work. I tried a handful of fans I had laying around, but just couldn't get the balance right. They either sucked all of the mist out too fast, or mist just filled the bottom of the chamber, actually inducing a slight "downdraft". I intended to try it again, but I got busy and shelved the project. Since you brought it up, I will probably get my hands on more than one fogger, and revisit it. Thanks for watching, and thanks for the suggestion.

@@BornHandy well if you have a smaller tornado machine then it will fill the intire bottom with fog clouds, even if there is one fogger. it's a good idea to have a huge tornado machine. but mine is small and only uses one fogger. thanks for replying! 😁

Yes, you can use a humidifier, but I use an ultrasonic fogger in a bowl of water, and it works much better.@@Colossaltitannwkwbend

Sure, but its hard to see and will fog the viewing panel very quickly. Better with the fan and dry ice for sure.
