Salvage Yard: Block Penetrations

Re: A Thought Experiment - The Impersonator

Loved to read your thoughts in this post. What a great analogy […]

I would really like to hear your thoughts on Solid Condom or any block penetration effect. Because then also you show something that’s not exciting in the moment, but it kinda was looking back on it. But then it’s already over.—CW

I've mentioned this before, and I've had other people write me about it as well. For the impossibility of the effect, and how clean it is, block penetration style effects don't always get the strongest reactions.

This structure of a trick—it's a magical penetration, but you don't know the penetration is magical until sometime after the penetration has occurred—is one that I've always had better reactions to from magicians than regular people. It's not that non-magicians dislike it, it's just that the reactions aren't quite as strong. (I'm referring here to tricks like Brass Block Penetration or Industrial Revelation. I've never used the Solid Condom effect.)

My theory is this: the magician knows where the trick is going. So they know to get a good look at the conditions as the item is being penetrated.

The lay person doesn't know where the trick is going. In fact that's often part of the premise. They think the thing is just going through a normal matchbox, or an empty card case. And then… Surprise! There was something in there all along.

And they will register surprise at seeing the object. But I think a lot of that is just actual surprise at seeing this unusual thing. It's not necessarily a surprise that comes from fully grasping the impossibility.

After the block is revealed, you're asking them to do a lot of remembering. "Remember you saw the full outside of the box while it was being penetrated." "Remember nothing was sticking out where it shouldn't have been." "Remember nothing was snuck into the box after the penetration." They didn't know to be looking for these things.

Here are some approaches that don't require you to rely on their memory to know they saw something impossible when doing a block penetration effect.

Have them record it on their phone.

Then they can at least go back and see that they didn't miss anything when they watched it the first time.

Have whatever box is being penetrated wrapped or sealed in an envelope.

This prevents the idea that something was partially removed during the penetration or snuck in afterward. I used to do the matchbox penetration with it wrapped up like a little gift.

Tell them what's going to happen while the object is being penetrated.

"I know this doesn't look like much, but imagine it wasn't matches in there. What if it was a block of wood, or ice, or.… imagine something completely impenetrable, like a brass block. Then what you're seeing would be truly impossible."

Now they know to register the impossibility of there being something solid inside the box. They know to have their guard up that nothing is coming out or going in unnoticed.

And using this language still allows it to be something of a surprise when the brass block—which you framed as sort of a thought experiment—is truly inside the matchbox.

What you're doing here is solving the core problem in real time: you're telling them what to notice and why it matters, as it's happening. You're not asking them to reconstruct the conditions after the fact. They were there. They heard you describe the impossible version of events. And then the impossible version turned out to be the real one. That's a very different experience than just showing them something weird and relying on their memory to do the math.
