I have this effect where I try to make a silk disappear from my hand, instead flames shoot out of my hand and the silk has a big hole burnt in it. I did it as part of a comedy routine for my inaugral performance at our magic circle.
I'm busy working on my children's show and i want to expand my silk routine. I was thinking of including this as part of the whole 'magic gone wrong' theme that runs through my show. The effect is quite safe - (as long as I don't look down into my hand when the explosion takes place

I know fire is generally a bad thing in kid's shows because you don't want them to try and imitate you- but in this case I'm not lighting a match or anything - it just happens as a consequence of me saying the wrong magic words or something. What do you guys think?
Obviously the venue will be a major consideration and I'll clear it with the host/ess first.
