Cup Stacking

Cup stacking.  Have you heard about it?  Due to a "Cool Tricks" segment on a Yo Gabba Gabba episode, every chance he got, MJ would take our red Solo cups and stack them into pyramids.  For his birthday I bought him a real set of Speed Stacks as mentioned below.  He's actually pretty good!  He requested a speed stack t-shirt which my mom found online.  I think he'll love it!
