I don't really know, I would rather have the kids in groups of 5 or 6, and do some table-hopping stuff. I don't really relish the thought of having 20 kids staring at me at the same time. I'm kind of shy
. I'm working on my patter though, trying to teach them some stuff about safety. I'd start it off like, "If someone says to you 'Do you want to see some magic, well, just follow me to my house/car.' Don't, just say No thank you, and walk away. If he/she follows you, call for help." Then, I'd try to elaborate on that with other safety stuff." Sorry, that was kind of off-topic, but I don't want these kids to get hurt.
