What if you get most of the way through the trick, then realise that you don't have the gimmick?
I'm talking too far through the trick to pass it off as a joke without it looking amazingly crap
Jesss....this ones is tough...but it really depends on what kind of trick you are doing.
with a thumb tip, just tenkai or palm the switched item
with a doble backed card....maybe lick it so 2 stick as one
with any reveal gimmick (tagged, distortion, window) maybe just do an awesome colour change that is impromptu
with a prophet gimmick maybe just ask the spectator to take one bill and do a bill switch
with a loop or the tarantula...maybe just pray that god help you!!!
what if....an spectator offers you 200 bucks to reveal the cardini change or the clipshift or a trick that is above average?
let the avarice consumes you muahahahaha i´m kidding, I wanna hear an honest answer
