It seems like these are the big thing right now in schools. I had never seen one until last night we were out at the mall having dinner and there was a boy with his dad at a table next to ours. The boy dropped that thing at least 6 times...I can see why teachers want them banned from their classrooms!

apparently they started as ways to help kids with ADD/ADHD concentrate. Then they became mainstream popular because - distraction toy! Now some schools are banning them.

Do you know what these are? Have you had any experience with them?
