Here's my kids show routine. many of you will argue with the fact I do mentalism but kids love it frankly and the adults are more likely to book me for something. You definatly should do mentalism. I also do card tricks that I have found go great for kids but short on time they would be first to go. For a larger audience I'd lose the coin tricks.
Come out in chained and mention don't think I can perform then escape
Bite out quarter
King Solomon's drink (I wear a cape so I'm clean 360 degrees)
if I feel like it i do Infusion from Ellusionist
Healed and sealed
Cut and restored rope
If I can arrange it I do Fizz Master and shoot it into a towel someone is holding or out the window etc.. If its not the right situation, DONT DO IT!
Vanishing Bandana (my most popular trick, put a towel out under you though, you will drop bannana peices)
Remix (from Sankey Sanders session)
Children play with three foot canes (Tangled Web by Eric Mead) (greatest trick with an apearing cane!)
Bold Business Mind Stunts 1 by Patric Kuffs)
Into the abyss (Oz Pearlman) (I do this trick in every single show i do)
B2 bomber or equivalent pen through dollar on a largish bill
100 foot of rope escape (either get a parent to tie you or a bunch of kids)
Believe me, this routine works!!!!! If you have any questions feel free to ask me firstname.lastname@example.org
