If you are wanting to do a handcuff escape for boys/girls (kids I'm assuming here) and wanting a bit of a comedy type act with it...
I suggesting maybe doing a Thumb cuffs routine.
The cuffs are examinable.. not gimmicked.
you can lock them up first (if doing close up) and then they get to lock you up.
as soon as they put a hankercheif or cover over your locked thumbs, you immediatly grab the keys from you pocket and put them in their hands while telling them that they had better hold onto the keys so you can't escape. (while you just did with one hand).
You put your hand back under cover and immediately jerk the "cheif" off both hands showing them they are locked up tight.
YOu can repeat with one hand, or the other hand, and even make the cuffs dissapear at the end of the routine.
Cost is inexpensive, they pack well as they are small, and its a fun routine to do.
