Query: Don't Waste Your Money !

I purchased this for my son, who loves studying severe weather. It worked exactly ONCE. It made one funnel cloud, then it burped a large air bubble inside and that was it, no matter which way it was turned, spun , or shaken. Now, it is just a tube of water with glitter that does NOTHING. And of course, it costs more to ship back for a refund than the value of the item itself. As I said....JUNK.
