So an "Imp" is something you do to make the magic happen.
A snap is an Imp, because it's the impetus behind the magic. "This card will rise to the top when I snap my fingers." It's just a hackneyed an uncreative impetus.
The Five Movements I wrote about in this post would be another Imp. "The magic happens when I do the five movements." That would be another physical impetus (like snapping) but one that has some element of mystery to it.
Using a magic word is a verbal impetus. Doing a half-mumbled verbal incantation might be a more interesting and mysterious verbal impetus.
If you're stuck on a presentation for an effect, I recommend you think instead about the impetus for the effect. Let's consider an example.
You have an effect. Let's say it's a ball that changes color and then grows in size.
The magician-centric presentation is, "Here is a ball. When I snap my fingers it will change color. When I say the magic word it will grow in size." The focus is on you and some half-hearted meaningless imps.
However, you're a more evolved magician now, so you think I'm going to give this a presentation that truly connects with people. But you're stuck... what's it going to be about? Maybe the ball represents something? Something that changes and grows? Cancer? Aw fuck, that's a terrible subject to build a trick around. Hmmm... maybe something about how we can all change and grow... something inspirational? Would something like that come off as anything other than trite garbage?
Stop.
Thinking directly about the effect and trying to come up with a presentation that maps on top of the effect is probably not the best option.
Instead think in terms of impetus. The ball changes color and grows when...what? Maybe the ball changes color and grows when your spectator smells the scent of some black tulips you have in a vase on your counter. What might that be like? Your friend comes over, notices the flowers and comments on how strange they are. "Smell them," you say. She does and you give her a half smile. "Notice anything?" you ask. She looks at you quizzically. You look around the room for a bit. "Let me grab something," you say and pick up a ball from your kid's toys. You wave the ball slowly back and forth. "Anything unusual happening?" you ask again. She starts to say no, but then the ball changes color and a moment after that it grows in size.
"Don't worry," you say, "the tulips have a mild-hallucinogenic effect. But it only lasts a few seconds." And you toss the ball back in the toy chest.
Putting your effort into creating an interesting impetus for a trick is a short-cut towards creating unique experiences for your audience.
I think every amateur magician who actually performs frequently for people in their life has noticed the diminishing reactions their effects get over time. And that's because, often, our tricks deliver the same experience time after time. "He read my mind to know what picture I drew." "He read my mind to know what word I was thinking." "He read my mind to know what the code to my phone was." That's all pretty much the same thing to a person. We think it's different because we're fascinated by magic so we notice the subtleties, but to the layperson these are all nearly identical experiences. You can watch someone paint a mountain or a river or a forest, and those are all the same experience for you despite the different subject matter unless you yourself are enamored with painting.
The best way I've found to prevent the diminishing reactions is to differentiate the experiences. And the best way I've found to differentiate these experiences is to differentiate the impetuses for the effects.
This is a subject that genuinely fascinates me. I have a document with over 60 Imps on it right now in all sorts of different categories. (Physical Imps, Verbal Imps, Procedural Imps, Sense Imps, Mystery Imps, among others). And I've been performing as much as I can recently to try out some of them and it's been pretty amazing. Tricks that I formerly had no real presentation for—ones that I would just use the Peek Backstage style for—have new life in them when prefaced with an intriguing or mysterious imp.
That being said, I also realize this is probably of limited interest to a lot of you, so I'll try not to get too swept up in writing these things up for the site.
But I want to leave you with one of my favorite imps that I've been using whenever I can.
The Pulp Fringe-Imp
Think of all the self-working or mostly self-working card tricks that have been released in recent years—entire DVD sets devoted to these types of tricks. Pick any one you like. Ideally one with a lot of dealing and counting and other process, but one that still has an impressive outcome. The type of trick that often people think isn't "commercial" enough to perform for real people.
I've been using this a lot with John Bannon's Collusion. In that trick I would have you and your friend each deal down any number of cards you want in the deck to select any random cards, those random cards are used to create another card, and then the free numbers you chose are used to find the card we just created.
The Pulp Fringe-Imp is a way of taking effects like these, that often come off as procedural puzzles, and turning them into genuine mysteries.
Here's how it works.
I come into the room with a deck of cards and a small suitcase. I open the suitcase and a light from inside illuminates my face.
