I don't know the best way to describe them, but I'll try.
You know those toys you give kids to play with that have wood bottoms and then a plastic "course" that they slide one end of the ball from to the other? They loop around and such. The bee is the same thing. They are attached to the metal rod, but you can slide it from one end to the other. Many of the kids grabbed bunches of them, instead of just sliding one.
Oh, I was thinking you were saying it was something you could take with you. I understand now.
