Harapan Ong has caused quite a stir online. With his technical style, he was able to do things that no one understood. Some people called it CGI, and others knew they were in the presence of a living legend. With his natural style, he can pull off just about anything.

Principia
is our favorite kind of book: one where, on every page, with every trick Harapan Ong
describes, you follow the text step by step with full attention. Principia is by Singaporean Harapan Ong and contains over 60 effects that are fun, practical, and highly innovative. In short: highly recommended!

The concept of Principia is actually very simple. A magic book combined with a scientific treatise on physics. By day, Harapan is a physics teacher. He brings the same laser focus and precision he uses in the classroom to this book.

The book contains impromptu magic, gaffed card magic, and dead-simple tricks that work right away on the first try. We predict that Principia is going to become a new classic. With 253 pages, this book will keep you busy for a while.
