"Absolutely fantastic. Super commercial, engaging, easy to do and instant reset. Superb!" - Chris Congreave

"Stroop Test ticks all the boxes. Captivating, engaging and magical. The method is devious, making this a magician and audience pleaser." - Joel Dickinson

"I've been looking for a good Stroop Test routine for ages and I finally found it! This is commercial, it makes sense and is going straight in my close-up and online sets!" - Luca Volpe

"A clever method hidden within an interesting presentation. Win-win." - Manos Kartsakis

"This is exactly the kind of magic I love. Clean, smart, strong, simple and very practical." - Haim Goldenberg

Predict the future using a simple psychological experiment that your audience won’t see coming. Created by David Jonathan and Nikolas Mavresis, this effect blends real science with real magic to predict your spectator’s choices 100% of the time. This is The Stroop Test.

Here’s what happens:

A set of cards is introduced that have the names of the colors printed on them. Each of the words is printed in a different color than what it reads. A spectator is asked to choose a number, and the magician deals down that many cards. The color on the card is shown to match a prediction the magician made before the trick even started.

The Stroop Test comes with custom printed cards that do all of the work for you. There are no complicated spelling procedures or unusual methods of displaying the cards. The number the spectator says is the number that you actually deal. Multiple clever principles interlock to create an engaging and baffling prediction effect. Start testing your audiences with The Stroop Test.

Lovely Report this review
Verified buyer Pro Privacy ON (login to see reviewer names) on August 4th, 2021
Lovely routine, excellent approach. Dan Harlan does a tremendous job in his explanations - Dan at its best ;) ... Easy to blow it up so that you can use it also stand up or stage with some little adjustments - I did already and made up laminated cards in DIN A4 /app. "letter size"). Little hint (helping to strength the theme of influence): I printed the word "Stroop" (only this word...) in blue.

Great hook, underwhelming trick Report this review
Verified buyer Pro Privacy ON (login to see reviewer names) on January 14th, 2022
I love the idea of using a premise borrowed from experimental cognitive psychology for a mind-reading/magic presentation. This is just a fairly simple, slight trick and doesn't explore the premise's full potential. At heart it's a very simple self-working card trick of the sort you already know how to do. The rave reviews show how far we've slid as a community when it comes to putting presentation first. Just feels like the excellent premise deserves better exploration and, hopefully, a stronger resulting trick.

The Effect Outshines the Patter Report this review
Verified buyer Pro Privacy ON (login to see reviewer names) on August 25th, 2021
The Stroop Test is an engaging piece of mentalism that is simple to do and immediately captures the attention of spectators. That said, most performers will want to rework the two different versions of scripts offered with the downloadable instructions. One author presents the effect in a straightforward narrative that lacks the creativity afforded by the effect. The other author couches the effect in some psychobabble about conscious and unconscious minds that most educated adults would find scientifically thin. Bottom line: buy this trick but turn your own creative juices loose and come up with your own novel presentation.

Ok, could have a much better Report this review
Verified buyer Pro Privacy ON (login to see reviewer names) on January 20th, 2023
This is an old trick you probably learned as a kid in new clothes. Using the Stroop Test is a very good idea. Too bad they did not take much advantage of this. 

1) It is ok but could have been much better. The patter is really limited when it could go into the Stroop Test in much more in-depth. Do the research to add that to the routine. Too bad they were lazy. 

2) For the price, they should have used plastic cards so they don't wear easily. They were cheap.

3) The colors are not all great. The brown looks black, the orange looks a bit like red.

4) They should have included a wallet for the cards. They were cheap.

I am very disappointed in this. The trick could have been much better. I have a hard time believing this is one of Dan Harlan's "go-to" tricks. Also, you won't be terribly successful doing this on stage, at least with the props. provided.

I don't think I will be using this.

Thank you, thank you, thank you! Not just for the great trick (and it is), but, as a fledgling magician, I really appreciated the insights given by everyone in the video. They not only showed three different performances which helps me design my patter, but they gave multiple, very helpful tips after the explanation to clarify ways to make the performance more...seamless. Great job!

Stroll Test Report this review
Verified buyer Pro Privacy ON (login to see reviewer names) on August 25th, 2021
Hey There, I purchased the Stroop Test, I played around with the card for a short time, Opened up the unbelievably detailed video and before you knew it, I had the presentation down pat. After showing the trick to several unsuspecting spectators, I was able to put my own pin on the trick. All I can say is, Great Trick, Leaves your spectators wanting more and if you haven’t ordered your, What the heck are you waiting for. Honestly, it’s an easy trick to learn, If a pineapple like me can learn and perform it, you’re way ahead of the game.

From known creators David and Nikolas, presented by P3’s WHEESAALL - Dan Harlan, they give you the best instruction, high quality cards, patter, explanations.. even you will have fun performing and practicing yourself. The STROOP TEST will stand out FROM THE REST, and as I put this to rest…. I’m sure you will see strong reviews alike any P3 exclusive. So strong that I would nominate this for Trick of the YEAR 2021.

This is the ultimate packs small plays huge. Look no further… add to cart! I do have some lyrics for you (mainly as a musician/ studio engineer all my young years) I shall make this short and sweet…


David, Nikolas, Dan & the P3 crew,

So SIMPLE yet so CLEAN!

Great little gimmick, with limits Report this review
Verified buyer Pro Privacy ON (login to see reviewer names) on September 22nd, 2021
Very fun little trick, can be presented a number of ways. If you're life is even remotely related to psychology, medicine, art, etc. you can naturally present this. It can only really be done once within a group of people - once someone has seen it, you can't perform it again even if they didn't "do" it so its best 1:1. And one reveal is just so much better than the other, I find myself praying for it. But, for what it is, its a lot of fun and the various presentations and methods allow you to adapt the concept to other "make your own" tricks. Worth the buy.

Stroop Test Report this review
Verified buyer Pro Privacy ON (login to see reviewer names) on August 30th, 2021
I just got this in the mail today and I had to watch the downloads. The downloads are amazing. David Jonathan and Nicolas Ma res is came up with an awesome effect and Dan Harlan did an incredible job in teaching it especially with the little details. It is well worth the money and then some.

Love it Report this review
Pro Privacy ON (login to see reviewer names) on August 6th, 2021
Nikolas Mavresis showed this to a virtual lecture he did for our club and I was immediately in love with it (I already knew what a Stroop Test was). The presentation gets your audience hooked right from the start and the final reveal will "get them" for sure.
