I wouldn't expect anything less from talented and creative working magician Matthew Johnson!
Not only is this a practical, real-world effect, but there's much more: when you purchase this effect, you also get an effective, and easy-to-execute card-force which you WILL use! So you're getting not only a dynamite close-up illusion with simple props, but a BONUS and priceless utility move, worth far more than the overall price of the effect as well.
Matthew has obviously worked out all of the kinks in the numerous times he's performed this in his close-up/surrounded-work-venues: even the force is angle-proof, deceptive, and easy-to-learn!
In this audience-participation gem, a borrowed bill, and randomly-selected card are used to create an eye-popping illusion that will be the talk of the evening/event. Likewise, the gaff (which is simple to make) is subtly, cleverly, and innocently worked in and then out of the presentation.
The overall quality of the video is good, and Matthew is a great teacher, explaining step-by-step how to make the gaff, how to execute his force, and breaks down the routine in an easy-to-follow manner, including some tips and psychological subtleties. Of course, the effect is shown several times in real-life conditions, as Matthew performs it in the video with patrons at a restaurant/bar.
As a working pro with more than 30 years experience, I highly recommend Matthew Johnson's "Melt" for hobbyists and pros alike. A BARGAIN at half the price.
