Tornado Maker, Weather Toys, Ultra-Light Aluminum Connecting Tube, Including 2 Empty Bottles, Watertight Tornado Toy, Suitable for Kids' Science Experiments (Blue)

This is sooo fun even if we don’t have bottles it still great!!

Easy to use and straightforward. The bottles are smaller than I was expecting but it still works (or rather, preschoolers can still get it to work before it empties). Small enough that I can include filling it, carrying a full bottle to the table, and emptying at the end as steps of the activity

worked great for my sons science fair project

Small and demonstrates tornado but you have to play with it for a while to figure how it can work consistently

I love learning toys and I often buy them for my niece. This is one of the nicer ones. It includes everything you need in the kit including the little bottles. The connection piece is very easy to screw on and doesn't leak.

Crap. Don’t waste your money.

It was a gift for my 4 year old nephew and he loved it!Love that it is small and easy to use for him.

My step son loves tornadoes, we put this together, he had a hard time initially making thr twister, but he did get it
