This really is genius. Not totally inspectable but I've learned to target my magic less on people who can't stand not knowing how something is done and more on most people who really love a great magic trick, which this one is...

Effect is great IF you can get it to work. The tutorial is very short and does not go into much detail, not to mention there's no verbal instruction through any of it. I personally had some questions for how exactly certain things work. Also, is not inspect-able in the slightest, which is a damper. Still looks cool, though.

Smartest method I've seen in a long time. Maybe even worth buying just to see how it's done. However, only 4 stars since it doesn't work with all straws.

After buying Break, I got Mask of Sanity. Once again, clever method. It is so clever actually, that it made me smile. Good!

This trick is really clever! Spactators will be speechless after this trick and they will never know how you've done it! Good job, completely worth it.

Outside of the box thinking. Very genius!!!

This is fantastic. I've just watched the explanation and it really is genius. I laughed out loud. I've not even tried this out yet but I can't give it anything less than 5 stars as it's just excellent.

Kevin has taken an old concept and placed it in a new setting. I love when I see this happening because it just goes to show that the old can be new. This is super simple and can be done with virtually any bottle which I love and the visual nature of the effect is awesome! Definitely a nice effect to have with you anywhere there are bottles.

Great effect, really clever adaption of this principle. Highly recommended!

Missed seeing things from Kevin and I really love this mad visual effect!

In my opinion, this is the best object in bottle effect I have seen in terms of method and impact.
