When I attended Fism in The Hague last year, I had the chance to watch John Carney lecturing.

When he explained his routine called Silver and Glass, he told us that Vernon had always encouraged him to experiment, to build on the work of past masters and to solve little problems that always exist in any routine.

The idea of finding "problems" to solve was a very exciting idea to me. So I started looking for "problems" and I would like to submit to you two of them from one routine which I think I have solved until someone of course finds that my solutions have problems to solve...

So here are the "problems" I suggest to you, hoping someone else will also post a problem to solve:

In Genii volume 65, number 6, Michael Vincent suggests to discover a Larry Jennings'trick called "Look-An Illusion". You can read this trick page 31 of "Larry Jennings on card & coin handling". Michael Vincent says in the article that to his knowledge "only three magicians perform this effect". So I read the description of the trick and realized how difficult it was to perform the trick properly. Moreover, you finished the trick not clean at all. So in fact to me, two "problems" to solve but at that time I forgot about the trick as I suspect many did. But a few days ago, a friend of mine came back with this trick and told me he had solve those two "problems". So I tried to solve them too.

Would you like to try to solve those two "problems"?

Here is a short description of the effect for those who do not have Jennings'book:

First you show you have a packet of four jokers and one ace of spades, then, you show you have a packet of four aces of spades and one Joker and then you show that you only have four kings.

I do not ask you to give me your solutions, I would rather have some other problems to solve.
