This is charming, but it's odd that the instructional video never mentions the actual name of the
item, which you should probably know if you're going to talk about it with any credibility -- it's
a "View-Master" and you can still buy them for about $20
The demo video is artfully edited
to omit any hint of the method. Anyone will experience will suspect how this works, and that the
video might be fishy. You'll be right, but the trick may still get you pumped. Just beware that the
actual process during performance is different than what's shown, except in 1 case out of 7.
Absolutely correct about the demo video. It is misleading, as it downplays the main method, which often turns out to be long and tedious. I also can't see repeating the effect for the same audience. And the viewer gets stuck easily, too. I was disappointed in this item.
