Wow what a great lecture! As most magicians who were struck with the magic bug at a young age will know Tenyo is great place to start as it's easily available in joke shops. What I'd forgotten was just how clever and well made these items are. I'm a born again Tenyo fan and will be looking to get some of the items Ian so ably demonstrated. The Nintendo DS Magic Fun game was amazing, and I'm disappointed to say I had it but didn't find the hidden effects Ian showed. Although Tenyo can seem plastic they are so inventive.
