There are so many possibilities of what you can do with the tornado, you can make it thin and rotating very fast or thick and very slow rotating, all you need to do is alter the pipes and fan speed to get what you want. If you'd prefer you can add Dry Ice to the water bowl for a more dense fog and more visible funnel. The only thing that I'd like to be enhanced is the plastic used because it feels very thin and not very durable. Overall I'd rate this product the full 5 stars. The shipping was also very fast, I ordered it November 29th and it was at my door step on the December 3rd. Also great for a gift anybody can love this!
The item works EXACTLY as advertised. I can't believe it... that is a rarity. You get a genuine 18 inch tall 2-4 inch wide tornado trapped in a display. This has my son virtually hypnotized. me too, actually. It's one of the few things he plays with that I also get a lot of enjoyment from. In fact, I'd say it is an appropriate gift for adults as well. It's that cool.
There is a big bowl of water involved as a source for the mist. So be aware of that. It is very quiet. Only issue I have is that it is a little rickety, due to the way it assembles. The vertical tubes are held into place with loose rubber grommets to make a seal, so you need to be careful that you don't bang into it much. For what this item cost ($250?) I'd prefer a more substantial "feel" to the item.
Even my wife... with her PhD in Chemistry... thought it was awesome.
Altogether a solid "A"... only thing keeping it from "A+" is price and the rickety feeling.
Adding an additional set or two of velcro straps would help.
Adding a light at the top that shines down would help illuminate the mist vortex.
The product works better with dry ice and hot water.
The plastic is very, very thin. I am not sure why the bottom half does not have pole sockets like the top half.
I wanted to get one of these machines for myself but 1) i had a hard time finding one, and 2) now that i have, its a little outside of my price range! I'll definately be saving up for one of these babies in the future!
