So I have been working for a while on creating a viable magic trick which makes use of memory techniques. Obviously just memorizing a deck of cards or 100 numbers is impressive, its not really a usable skill. You cant just say to your friends 'hey give me 5 mins and i’ll memorize this entire deck of cards. It comes off as showing off and its bloody boring for them to just have to sit and watch you memorize then recall the deck (unless your really good obviously).
So my solution is actually fairly simple and I use it when performing magic to build my credibility. All you do is divide the deck into two half’s, one which has the hearts and spades and one which has the diamonds and clubs. You then allow your spectator to shuffle one half and hand it back to you. You then memorize it and hand it back to him. You then take the other half, reorder them into the same order as the other half so that the colors match up (spades with clubs, hearts with diamonds.) and then you simply deal both halves out proving they are now in the same order.
So why does this work? Well there are two reasons. The first is that people outside the memory community aren’t aware that memorizing half a deck of cards is as easy as it actually is. To you only memorizing 26 cards may see ‘light weight’ but it isn’t to your average joe. They will still be stunned and believe you are some sought of savant. The second reason this works is because memorizing half as many cards is exponentially easier than memorizing a full deck. You can practice an get really quick at 26 cards and your times will likely be below 50% of your full deck time. For example I can do 26 cards in under a minuet but still struggle to do a full deck in under 4. Doing so also doesn’t hurt your long term memory aims either as memorizing 26 cards can easily be built on later on.
Let us know what you think. I’d love to hear how others have used memory as a tool to do magic.
