Well if you havent tried to perform it in person yet you cant really say that.
It works great in person.I mostly get stunned silences first and then mini freakouts.(I learned it awhile back with the Dangerous dvd.)
You just really have to know how to build it up.And sway the audiences to the right angles.I usually say stuff like "come over this way so you can see better.."or anything like that.
I usually perform this in a cyril takayama sort of way.
That man makes a simple crazy mans handcuffs look like a f'ing miracle.
