This is one of those effects that will make you say, "Why didn't I think of that?!" The method is so
simple and direct that you wouldn't be blamed for doubting whether this effect will work or if
you'll be caught.
Practice this effect until you master it; have a well thought out patter,
polish your audience management skills, and this effect will work. The effect isn't highly dependent
on your audience but if you have little to no audience management skills, this effect may not work
well in your favor. In my opinion, your patter and how you present the effect is very important. If
you perform this effect with Mickey Mouse-like patter, you may have no "wow" factor or worse,
someone will figure out your method.
I rated this at 4 stars because Oz didn't cover an
important detail in the video regarding a function of the iPhone. This detail is important because
if it's not taken cared of during the performance, everyone will know your method. I'm sure
performers have already mentioned this detail in the forums but I'm having issues logging into the
forums so I can't give my two cents. Once you know the method you'll figure out this important
detail. With some time, you can find a way to fix this issue. Other than that the video, the
explanation, the tips and advice, and the bonus effect are great! The effect is practical, simple to
do, uses an object almost everyone has (this will work with all model iPhones - if their contact
list can scroll up and down, it will work), yet plays a BIG impact. I highly recommend this effect!
