Query: Flat

I bought this for my 12 year daughter for her birthday. We followed the directions step-by-step and all it did was sat on the ground and sprayed water. Then she thought you would have to move it to make it go up in the air, like the picture, but as soon as she moved it it exploded and ripped. It was a flat disappointed on her birthday. She wants me to buy another just for memory sake but, I would not recommend it for anyone. It was a great disappointment.
