How about David's Magic does something that's completely different?​

 

Here's a great idea for the older kids that will get them involved...and having a lot of fun too!!

I can do a half-hour workshop for either JUGGLING or BALLOON-MODELLING that will give your kids a taste of circus skills and may just get them hooked!! This starts off with my stand-up routine and then is followed by a hands-on lesson- juggling for up to ten year olds, balloon-modelling for smaller hands.

It's a great way to get your party talked about!! By the way, I have enough balls for thirty kids, so this should suit your 'invite-the-class' type of party. And this can be combined with a half-hour's formal show.
