I always present this effect as a way to magically move the doll and my patter storyline might not make sense to some pople but as long as they can visualize similar scenes that they've encounter in the movies this effect will take their breath away. I understand your comment perfectly about the silence, but for me, I think that silence goes better during the rise, but in the beginning you have some kind of patter (make sense or not) that leads into this effect. If you decided to get this effect, the method can be applied to anything else other than the doll. You can even make a candy cane rise up using this method.
Just to clear things up, I have nothing against your presentation.
Also, I don't see anything wrong with saying they're no strings, since they're really aren't any.
Anyways, thank you for your time to reading my post and I wish you all the success.
I read before Strong Magic by Darwin Ortiz and I read something very important. Here's the message Darwin said in my own words:
Things that are not important should not be given importance. You give it importance, it might diminish the effect. Saying there's no strings does 2 things to your spectators. First, many spectators know nowadays about strings, but keep in mind, there's still some who don't. If you say there's no strings, you've given them information that some magic is done with strings. And the second is, because you've said there's no strings even if there isn't really any strings, you've given them a method which will diminish the effect and might portray you as a trickster.
