What our customer's say!

"Kids loved it, but it's not durable", It didn't leak, well at least not yet, but it sure felt like it was going to given its construction. The kids loved seeing and controlling the whirlpool size.

"Tornado Lab from Discovery Toys", I bought this as a Christmas gift for my grandson. I ordered one and the plastic case was scratched so Discovery Toys sent me another one free of charge. The other one was scratched also but I kept it and my grandson really likes it. And as far as customer service is concerned, I was very pleased.

"Still used after two years", Early elementary kids have loved this toy and gotten it out to share with friends several times. It's a toy that you use for 20 -30 minutes - trying all the levels - and then it is put away until next time. But it comes out again and again. Easy to use, easy clean up.

"Not worth it", This worked greaet for two days. There is a degree of seperation between all the different tornados, but not impressive. you can make better tornados with pop bottles. And it is not waterproof, and my son overfilled it, ruining most of the electronical parts. Has good information on tornados, but you can find the same stuff anywhere.

"A Good Model and I Should Know", This toy is versatile and can be used at many levels. Early learners will like the Halloween-y howling sounds it makes, and will like to watch the spiraling shape. More advanced kids can study specific gravity and weather patterns, as well as learning about the more notorious tornadoes in US history. The tornado lab is fun to use with food coloring in the water, to show how air masses collide; also fun to vary the little items dropped in. Just as in real life, the lighter lower specific gravity items are captured in the vortex and carried up; the higher specific gravity items are tossed out. (I should know; I survived the 1965 Palm Sunday tornado in Indiana. One of my Dad's checkbook registers was returned to us from central Ohio.) We really think this is a fun toy, even for phobics, and we have used one up already and are on our second.
