grammy got this blue ball because she thought it was neat, but i really enjoy it too. the "ball" is made up of many individual pieces with very strong magnets inside. the magnets help you to put the ball together in the right way. at first, i would only take out one piece at a time, and then put it back. but now i can remove 7 or 8 pieces and i am still able to put the ball back together! it gets more and more difficult when i remove more pieces, but i really enjoy the challenge. if i put a piece in the wrong place, i don't get frustrated -- i just try to figure out the right way to do it. when i put the ball completely together, i get SOOO excited!
