I also plan on using it for movement breaks and as a reward.
It is Bop It!
It's a bit addictive. My son received one for his birthday. I'm proud to say I am the high score holder in our house.
When you start it it plays a funky little rhythm and instructs you to bop it (hit the center button), pull it (pull a handle on one end) or twist it (turn a knob at the other end).
You can play as an individual or as a group. When playing as a group you need to "pass it."
They sell them at Target and Walmart and the like. They are under $20.00.
Good times people, good times!
