They have them here at a store named Spencers. I think I have seen them at Toy R Us too. I loved those, you can't shake them though because the bubbles, so I always got the answer "not likely". Maybe that was just my luck though. Not of the stuff I asked about ever came true anyhow.
Still very fun! I have a magic 8 ball at home. Except I've used it so much that the inside is all bubbly and its hard to see the words sometimes... but I do have one. And I like it. :D
