hehe...pass the parcel would be fun, except they think theyre passing around a parcel containing something...except when they open it, it has vanished

...yes lame i know but im sure theyd like it...hehe grand prize could be that they get to keep the "full" parcel...
also...i did a short lil routine in a school classroom with kids once and i didnt know how i wanted to open up and start the routine...so i actually started off by explaining that i needed to warm up my physcic powers before i started, and did that my mentally figuring out the kids names...ofcourse before the show started i simply asked the teachers wut the name of some of the kids were and then simply revealed this by explaining that i knew there was a "john" in the room..and then id lead myself to him somehow...wow...they got such a kick outa the simplest effect..
