Hey Pete I am always willing to lend a hand when it comes to giving advice because it also helps me. And tannoy for taking my advice onboard, I don't always agree with the advice I recurve but I always take it on board.
I understand you enjoy this effect but sometimes you should not perform your favourite effects all the time. There are certain things I love that won't be performed more than a handful of times a year. I personally would not perform this effect for children, for the reason I don't believe they would appreciate everything that is going on, especially within my presentation. A truly great magician knows what to perform and when. And more importantly when not to perform. it should be said I have never done kids magic so I am not sure what works for them but I have spent a lot of time around children so I have some assumptions as to what will.
I can understand where you are coming from with your beliefs regarding performance considerations, however may I ask why your audience is the only person you should care about and you should fine then the strongest effect possible regardless of the method
I would have to strongly disagree on your advice on not performing this effect for children because I've performed this effect hundreds of times for children and it is the effect that gets the strongest reaction in my show. You might not believe this but please do believe me when I say that it is completely true. In fact, the reality is quite the contrary of what you said, the children understand exactly what is going on, whenever they see that doll rises, their smiles, amazement, and laughter really made my day. Therefore, I will definitely continue performing this effect for children.
I've also tried many of the PK, levitation and animation effects utilizing loops, IT, rings etc...and I hate everyone of them. In my honest opinion, I believe that the rising doll is the strongest animation effect as well as having a very practical method. You don't have to worry about lighting, breakage, or get readys of any sort, none of the effects that I've seen fit into these criterias.
Also, the most important reason why I love performing the rising doll besides the fact that the effect gets amazing reactions everytime, is because I can concentrate solely on presentation without having to worry about any other factors.
