This guy I know has the coolest thing in the world. It's a rubber ball filled with some unknown substance that kind of looks like shampoo. It's attached to a rubber thing with a loop to go around your finger so you can throw it down kind of like a yo-yo. If you spin it, it flattens out and kind of looks like a UFO. Apparently this thing is all the rage among elementary school students in New York and LA, though some schools have banned it because no one knows what the substance inside is or whether it's toxic. Does anyone know the name of this or where I can find one? I'm desperate. I need one NOW. Leave a comment, please, if you know anything about these things.
