Very annoying!!!!! ### 3/5 — ???????? *2014-03-11* How to use it Please update it and put a video that shows how to use it??? ### 5/5 — Wonderfully Easy *2013-10-22* This little app literally packs small and plays big. I got it when it first came out. The graphics are gorgeous, the instructions are oh so easy to follow and it will fool the best of them. It harkens back to the golden age of magic with tomorrow's technology, hidden under the hood. It is created by a professional magician for amateurs, hobbyists, and pros and is just fun to do. Bottom line: get it. You'll love it. ### 5/5 — Simple and fun! *2013-10-22* If you're interested in getting into magic or just want some magic for kids (or kids at heart,) this is it! The instructions in the app are awesome. It took me a couple of minutes to learn. They first explain how the magic works, and then give you a terrific way to perform it. I like that style because it gives you tips about how a pro does magic and how to be a performer and not just a lazy uncle! You do have to print out cards though, but that adds to the magic! If the cards were digital, no one would be entertained because they would know it is just computer coding. The physical cards mean everyone wonders how it works with the app, making it suspenseful, intriguing, slightly skeptical, and thus... Magical! I look forward to more apps like this one. I hope they can use the same cards or similar variations so I don't have to keep too much in my car or wallet. (I printed out on small pieces of paper. They don't have to be big, just make sure you can't see through the back!) ### 1/5 — HORIBBLE *2013-06-26* Horrible horrible horrible. ### 5/5 — Phenomenal Trick! *2012-07-23* Great complex trick with a sophisticated yet simplistic designed app that will be sure to leave your audience speechless! ### 1/5 — Rubbish *2012-07-21* It is rubbish don't waste your time ive just took up lots of room on my I pad and you have to download these rubbish posters anyway don't waste any of your time ## Frequently asked questions about Prof. Marvel's Crystal Ball ### What is Prof. Marvel's Crystal Ball?
