- tepidpond, on 10/12/2007, -2/+19More pictures and more than five words of text would be nice...
- NJank, on 10/12/2007, -1/+11if by entertain, you mean maintain and stimulate interest, as well as provide an incentive for continued attention, then yes, This is a primary goal of and challenge for any educator who wants to accomplish anything. If you can't maintain student interest, they won't learn, and you aren't doing your job right. It's your job to compete for their attention. If that drifts toward 'entertain', than yes, that's what you should do. If the material is boring, the teacher's job is to fix that problem, such that the students become amenable to the absorption of the material. Otherwise you may as well stay home.
- dbre2, on 10/12/2007, -0/+9I'd keep an eye on him...today it's a tornado, tommorow it'll be a sun...
- itsrainin, on 10/12/2007, -2/+11good grief, this is the thinnest article known to man.
- Cputerace, on 10/12/2007, -3/+12The tornado simulation is not room size, its simply in a room. The tornado is no more than 1'x1'
They have a bigger one at the Museum of Science in Boston inside a 2'x2' glass "closet". - inactive, on 10/12/2007, -4/+13Hi Charlie Brown.
- iWorks, on 10/12/2007, -2/+10awaiting story of one of these getting out into the wild and really causing some panic
- mikm, on 10/12/2007, -1/+9I'd love to see a video of this
- carguy84, on 10/12/2007, -2/+10Ya, where are the flying cows, barns and trailers?
- MarkZahn, on 10/12/2007, -0/+8Did some Googling...
Here's Dr. Brey's description on how it's done...

More pictures...
http://baraboo-sauk.uwc.edu/academics/classresources/geo/cool_things.htm - AdamWillis, on 10/12/2007, -4/+11I just wish I had teachers who would do this. Then school would be interesting
- MarkZahn, on 10/12/2007, -0/+7I took Dr. Brey's meteorology class at UW-Fox Valley back around 2000 and have seen this done twice while I was at the University, so I can attest that it works and *does* look like a tornado. He's been doing these things for years. That picture they show is not the best. I have shot video of this... I'll see if I can find it and post it to YouTube. It is pretty cool if you see it in person, or if you see it from a foot away. I don't have the exact how-to on how to do it, but i know he fashions a square "pen" out of cardboard, and I think fans are put at the corners. I think he also closes up the room's heating vents and puts on a couple pots of boiling water to get the room humidity up. There's the dry ice at the base and the fan affixed to the ceiling. How and why all that works I don't know (I didn't do so well in this course myself).
(PS. I don't know if anybody's caught it, but in the larger picture, you can see the red and green Monopoly houses and hotels he likes to put on the ground to get sucked up into the tornado.) - carguy84, on 10/12/2007, -2/+7Really AvatarKava? Really? You can't? No way, we ALL thought you could...
Those who aren't laughing with iWorks, are laughing AT you right now =/
Chip- - adml_shake, on 10/12/2007, -0/+5Thats pretty slick....now they need to go build one in their gym and run it during a basketball game or something....maybe have some background music of buildings being ripped apart...
- iWorks, on 10/12/2007, -0/+4flying bovine = spooky
flying hampster = comedy - tuxidomasx, on 10/12/2007, -1/+5i would SO toss my pet hampster in that thing.
whoosh! oh man, that'd be awesome.
(just kidding. but not really.) - inactive, on 10/12/2007, -0/+3I did this in a first grade science fair with two coke bottles, some water and sealant. Made a pretty cool tornado/whirlpool.
- johndi, on 10/12/2007, -1/+4Looks like it is only closet sized. Maybe dry ice and a fan to make sure the water vapor rises, instead of sinking with the CO2.
- ziggystardust, on 10/12/2007, -0/+3This is neat but not great. I was expecting to see text books akimbo. Not Digg worthy imo.
- SweetChuck, on 10/12/2007, -0/+2Yeah it's great for high school demonstrations, but the one at Iowa State in Ames is much more impressive.

"Microburst and tornado simulators with 20 ft wide x 44 ft length x 18 ft high test section frame with capabilities for generating a translating microburst-like jet (6.0 ft diameter) and a tornado-like vortex (4.0 ft diameter) for model testing " - Jhorra, on 10/12/2007, -0/+2Cputerace
Maybe by room sized he's talking about hight, and not width. It does span the entire height of the room. - vonskippy, on 10/12/2007, -0/+2There's this new fangled invention called "Digital Video". Look into it.
- Wireddd, on 10/12/2007, -0/+2well from the looks of it they are using two common box fans attached to the ceiling blowing in opposite directions. They removed the ceiling tiles from the drop ceiling between the fans to allow the funnel somewhere to go and maybe they have another fan somewhere else in the ceiling which is pulling the air down from above the ceiling; though, I am not sure if this would be necessary.
- BLKMGK, on 10/12/2007, -0/+2www.weather-photography.com/techniques.php?cat=miscellaneous&page=tornado_machine
Plans to build smaller model. - crazyman, on 10/12/2007, -3/+5Awesome. Though it would be nice to see more.
- MOJIRA, on 05/17/2008, -0/+2wouldnt this be cool on a slightly larger scale and if it was incorporated into a theme park ride? you know that earthquake ride they have at universal in orlando, FL - it could just be an added effect and they call the ride the end of the fricking world instead. and yeah, flying cattle is always a plus...
- krum, on 10/12/2007, -0/+2That's cool, but it doesn't beat having a real one drop 50 yards in front of you... I still have nightmares about that.
- akira117, on 10/12/2007, -0/+1Johndi, they mean the size of the space, compared to a real tornadoes (the affected space). Not the size of the actual tornado itself.
- UltraNurd, on 10/12/2007, -0/+1There's a 6-foot diameter cylindrical open cage tornado setup at the Science Museum of Minnesota, or at least there was before they moved locations a few years ago. I didn't see if they set it up in their new building or not. They use a dry ice fog machine to make the vortex visible.
- lastingdamage, on 10/12/2007, -1/+2Because it IS cool, it LOOKS cool and it gets kids interested in science. Sometimes doing something just because you can is half the fun. I want one of these in my living room, sucking up all the cigarette smoke.
- v3xt0r, on 10/12/2007, -1/+2who's the gay guy saluting @ the tornado like hitler? weak
- MarkZahn, on 10/12/2007, -0/+1Video is up on Google Video!
http://digg.com/science/VIDEO:_Professor_simulates_tornado_in_classroom - FTLTorgo, on 10/12/2007, -4/+5Damn it, I'd really like to digg this story but I can't without seeing either video or instructions on how to replicate it.
- MarkZahn, on 10/12/2007, -0/+1I can personally attest that it is not fake, as I took that class at this University and I stood a foot from it myself. As soon as I can find my video from it I'll post it on YouTube.
- MarkZahn, on 10/12/2007, -0/+1See my links in comments above.
- bubbagump, on 10/12/2007, -0/+1Not as "cool" as the real thing -- but there's that death and dying thing. The issue is, understanding the processes that lead to tornado formation... It looks like this guy is doing a great job of showing how and why tornados form.
Needs more details, but this digg will lead to some great googling. - diggnationdevon, on 10/12/2007, -0/+1Very neat, however I would like to see more pictures and more details.
- bebop717, on 10/12/2007, -0/+1Meh, they have the same thing in both Boston, and in St. Paul.
No Digg. - iWorks, on 10/12/2007, -1/+2i think you are questioning it
- djdole, on 10/12/2007, -3/+3Doc Oc?
- UltraNurd, on 10/12/2007, -3/+3I can imagine the Fox special now...
"Tornadoes, nature's black holes, could be created in a lab and released in the wild..." - uman44, on 10/12/2007, -0/+0Theres an even bigger one of those here in Fargo, North Dakota and it actually looks like a tornado. Its in the little kids museum thing, but I have to admit, That was the only reason i went as a kid... its pretty damn cool.
- macphan, on 10/12/2007, -0/+0schweet
- alpha1125, on 10/12/2007, -0/+0I was in the Ontario Science Centre a few months ago. They've had an tornado generator for years. I remember it was around some 15 years ago. I'm sure other science centres have these demonstrations as well.
I don't know how this is new, or exciting. - ericsenf, on 10/12/2007, -0/+0There is a tornado machine similar to this at the Science Museum of Minnesota. The kids and I played with this for about 30 minutes during our last visit. http://www.smm.com
- Gauol, on 10/12/2007, -0/+0Didn't David Copperfield do this with a tornado of fire
http://www3.youtube.com/watch?v=p3AyBbIx4iM&search=David%20Copperfield%20%20tornado%20of%20fire - djdole, on 10/12/2007, -1/+1I thought the same thing, except I was thinking about the Detroit hands-on museum. Lame.
It's definitely nothing new. - dattaway, on 10/12/2007, -0/+0We made it snow in our freezer at work once by opening the dock doors and letting the humid air in the -10F degree, 40 foot tall room.
Now I know what to do with those crates of dry ice... - sbostedor, on 10/12/2007, -2/+2Blah - there's one like this at the Ann Arbor Hands On Museum in Ann Arbor, MI. It's cool but nothing unique.
- krakelohm, on 10/12/2007, -1/+1Is that Bill Paxton in the background?
