Thats nice steve ... have you performed it for a layperson yet? ... i can see how its done but i think thats because I'm into magic .... might have to try it on my brothers later and see what they think.
Yeah, have done it to lay people. Works well! Sometimes, angles do matter. It only doesn't when you do it well, which is only half the time for me lol.
To be honest I thought it was sloppy and the second change was quite obvious. The set up was dodgy as well. Your palm doesn't look natural and anybody (lay or not) would pick up on that.
