Ta Da, your toast is ready

Is it worth mentioning (I dunno as I avoid kids like Posh Spice) try and get the kids involved, a magic wand and a silly magic word the kids have to chant to get anything to happen (depending on age obviously) and get things like sweets to vanish etc in the bag rather than props you maybe can't afford, they are cheap and can be handed out.
Just a though though I have no idea if it's valid, lol.
