You can do this anywhere, even with a heckler, and it will fool them out of their mind! This is one of the best impromptu effects with a phone that I've ever seen! The instruction could be a little more detailed, but it's a free product! What more could you ask for!

Really easy to do and simple! Genius idea! Totally amazing, and it's free!

Really simple, really fooling. An instant 5 stars.

Genius! Simple yet amazing. I would’ve paid $10 for this effect. 5+ stars.

Great idea. Simple to do and impromptu as well.

Original, great idea; it's super simple, and can be done in minutes after watching. And it's impromptu, a quality I always appreciate when it comes to magic tricks.

Really good idea with everyday objects! Totally worth the 5 stars.

Great idea and super easy to perform. Instruction is a bit rushed however hence the 4 star review. Was a bit difficult to follow along but after watching a couple times I was able to get it. It's free so check it out!

Why didn't I think of this. This trick is great, visual, easy to do and above all it's free. Thanks I really like this and I have been using it ever since. Above 5 stars!

I like magic with everyday objects. And this trick is impromptu, uses borrowed objects and very visual. Simply 5 stars!

This is a very deceiving, mindblowing trick. You'll love learning it. The tutorial is quick, concise, and you can perform almost right away! I definitely recommend this.

This is an amazing trick and is super easy to do. The method behind this trick is absolutely incredible. This is a download worth getting because it is free, impromptu and can be done with borrowed objects. 5 out of 5 stars.

Simple effect that looks killer, especially since it partially happens in the spectator's hands. I've performed effects like these before but always with rubber bands; this version uses something the spectator is very familiar with and since headphone cables don't stretch like rubber bands do, it makes for a more visual trick. Well done!

Awesome trick, anyone could do this but it gives such a nice effect. Great for whenever someone asks you to do a magic trick on the spot and you're not prepared.

I can't find other words than "wow". I really like impromptu effects with everyday objects, and this is it! No gimmick, no setup, everything can be borrowed and it's easy. Spectators really love it.

Great, simple, impromptu effect! Nicely done! Easy 5 stars based on simplicity, genuine practicality, and instantaneous reset! Could literally do repeatedly to different people's phones down a line!

Nothing better than simple, visual, impromptu magic with borrowed everyday items. I'll be adding this to my go to effects when the items are around.

Genius effect, almost undetectable and incredibly easy to learn. The kind of effect you pull out when someone wants to see a trick and you have no props or gimmicks on you, however, it would be right at home anywhere else. I love it and I can guarantee you will too!

Great Impromptu trick using everyday items. Just about everyone has a phone and headphones on them. Using their phone and headphones just makes this even better. 5 Stars!

Wow. I do this trick to everyone and nobody gets how I do this. 10 outta 5 stars!
