Principia Principia Principia Principia Principia Principia

Singapore's Harapan Ong has caused an online sensation with his technical abilities. Videos began to circulate some years ago from a pair of hands doing extraordinary things. His style is natural, unassuming, and soft. But Aces appear, selections transpose, and magical things just seem to happen in Harapan's hands.

Principia is our very favorite kind of magic book: the kind of book that you pour over every page, trying out each and every piece Harapan describes. EVERY single effect in the book (and there are 60 effects described) is practical, and fun and radically new.

The concept of Principia is a magic book fused with a scientific paper on physics. By day, Harapan is a physics teacher and he uses the same laser-focus and precision in both his career and his magic.

The book features impromptu magic, gaffed card magic, and dead-on easy tricks you can do the first time you try. We predict that Principia will be the most talked-about card book of the year, and that it will be studied and returned to for many years to come.

The regular edition is the orange book photographed, and the limited deluxe edition of Principia is the blue book and slipcase.

Hard cover. 253 pages.

Customer reviews for Principia


Just recieved the book, everything in it is absolutely beautiful! Just a little suggestion, if the online performance videos are sorted in order and have an table of content, it will be wonderful.



Received my book 2 days ago. It is amazing. The production value is very high; the cover and binding are great and the paper stock is very high quality.
I’ve worked through several effects at the beginning of the book. I love the style in which they are written. They are set up like a science paper from a journal, and the format is very clear and uniform, making it easy to know where to find different bits of information when browsing routines. I love his footnotes and bibliography sections. He cares about magic as an art form with a history.
The effects I’ve worked, Streamlined Pocket Transposition and The Card Across, are very good updates to classic effects. They require some intermediate sleights, but nothing back breaking (yet), and the effects are clean and delightful.
Very pleased with my purchase, I think you will be, too.



This is a very nice book with a plush cover and large pages. I tend to like books written in a conversational style; this is a bit more technical in nature but it works. If you like cards this book is definitely worth it. There are two really nice extras as well. Although most card workers will already have the common gaffs needed for some of the tricks, they are included with the book. Also, for those like me that sometimes can't figure out what the trick is supposed to look like, there are video performances of many of the effects. Very nice job.



Vanishing Inc. and Harapan Ong have gone the extra mile to produce a book of exceptional quality, filled with interesting effects and essays. Providing a forty plus minute video showing nearly every trick really brings the material to life and I hope future products continue to offer this. Providing a good sampling of gaffs (matching bicycle decks) also makes everything really accessible, giving the reader no excuse to not jump in and start learning the material. Harapan's writing is clear, the illustrations are profuse and useful, the citations are good and the material is just plain fun. Highly recommended!

I received the book recently and I like the quality of the book and it is also well presented. It is also easy to read and understand, with a good video and gaffs card. If there is content of the effects in the video, that would be nice. Would definitely recommend to my friends.



This book is simply stunning. I am halfway through and already it is clear that the material in this book is going to have the most significant impact on my magic of any purchase since moving beyond beginner materials.

I, like many magicians, use books and DVD's as a source of inspiration for my own creativity. There's a ton of inspiration in here but most significantly there's a lot of material that I know I will do forever more exactly as described.

The whole package is an absolute joy and the extras are very much appreciated. 100%, no reservations recommended.



This is absolutely one of the best best buys I've made in a couple of years. The writing is clear and the illustrations are great. Being a hobbyist with intermediate skills, I have not found any tricks in the book that I can't learn with a little work. Would definitely recommend to anybody into card magic



Just got the book! Amazing tricks and well explained! I really love it



Had the pleasure to meet Harapan a few years ago when he briefly came to France as an exchange student and at the time, he was already way ahead of his peers when it came to magic. The book reflects on this: from great thinking to absolute pristine execution, all the effects are true workers. My best purchase of this year so far!



I don't leave many reviews but I need to say something about this book.....its gold. This. book will actually make you feel a little bad about your magic. Harapan has put so much good material in here that it will keep you busy for a long time. And if you're into arts and crafts, there are a few tricks that require some fun stay-indoor hands on goodness you can do to make some fun gaffs to do some amazing magic. Overall...one of the finest books I've purchased. Vanishing Inc Books are the new standard.



This book is fantastic. Harapan Ong has a really unique way of looking at magic due to his interesting background. Andy Gladwin designed the book and Joshua Jay handles the introduction and I will tell you the result is a book of really interesting philosophy and magic effects that rocked my world. Highly recommended. So glad I bought this book.

Any product Vanishing Inc. Is involved with, you can trust to be of the highest caliber, and this is no exception. Beautiful book full of wonderful, practical magic. One of the best things about this release is that you are provided access to online performances by Harapan of almost every item in the book — a wonderful way to enjoy the magic and easily ascertain which items you want to delve into.

Thank you Vanishing Inc for giving us such a treasure.



Excellent book, with a very good quality thick padded orange coloured cover, great introduction to the book, including how it came about for the art work & design of the book, continued with easy to follow discriptions of the different tricks, comes with the Gaff cards, which came in a nice presentation box, a good quality video production, demonstrating the different tricks, the page numbers from the book of each trick is shown at the bottom of the video.
