Mattel recently introduced the "Harry Potter Broomstick". It's a battery-powered toy that resembles the flying Nimbus 2000 brooms from the Harry Potter movies. The broom vibrates and makes noises when it's placed in between a kids' legs.

My 12 year old daughter is a big Harry Potter fan, and loved the part with the Nimbus 2000, so I decided to buy her this toy. I was afraid she would think it was too babyish, but she LOVES this toy. Even my daughter's friends enjoy playing with this fun toy. I was surprised at how long they can just sit in her room and play with this magic broomstick! A great buy for any Harry Potter fan! :)
hmm...I can't work out why it's so popular either.
