I have all these items I would like to perform at kids parties, do you think I have enough............the shows will be around 20-40 minutes long.
-comedy funnel
-zombie ball
-candel thru arm
-cups and balls routine
-sponge ball routine
-cut and restored rope
-vanishing crayons
-magic colouring book
-D'lites
-TT (silk routine, vanishing, reappearing, thru a kids ear, etc.)
-change cap ( havent thought of a routine with this yet)

That's about it. So what do u think?
P.S. i want to get a dove pan so i can leave the kids with candy or something.

You have more than enough. A 20 minute show should have 4 effects at most. If your presentation is up to par, you should be able to play out each effect to a minimum of five minutes. Now this may mean combining certain elements of your show to make it work (for example: Magic Coloring Book, Breakaway Wand, and Vanishing Crayons could all go together; I gave an example of a possible performance using these items in another Kid Show thread). Once again... you have way too much. Cut it down to a minimum, and use your entertainment value to make the show however long you want it to be.

Edit: I just looked at your list, and I noticed that you had the cups and balls on there... this routine alone could fill up 20 minutes, but kids would be bored. This got me to thinking that I forgot to remind that you want to play out your effects, but don't make them too long or the kids will get bored and their attentions will wander.

You have plenty of effects. Now! List the books and or DVDs that you've watched to show you what a kid's party is all about.
If you think it's your magic you are a step away at falling on your face. Good list of tricks, show us the other list.
