all this praise will swell me head
your absolutely right kids see and hear all.
when i do magic for kids i take the attitude that im being paid to show you magic wether you like it or not.
that said self working trick work best change bags mismade silks and the like.
if you expect the kids are going to tear strips of you then your prepared.
the classic cut and restored rope trick where the not slides up and down the rope before comming off the end is great, as they see you or have cut the rope themselves.
i usualy give the assistant the knot to take home and practice with, and if anyone asks what it is to tell then it a fraid knot (I'm a fraid not)
i also say to them before i start what is the difference between a fool and an idiot, a fool gets paid
if the kids get narky with you then just stop and say ive already been paid so i can stop now if you want

i dont get paid by the hour.
this works for discos as well, its a good way to control the narky ones as it sets the other kids against the problem one (funny they used that taktic often in schools).
remember when working with kids you are in control, you can dictate the speed, you can stop, pack up and go home anytime.
just make sure your paid before or when you arive and your set.
