Recently, I've seen Scare FX "cauldron witch" project, and I would like to do something similar, specially with the cauldron. But I am seeing this a little bit complicated, since the motor must have an electric generator, and such things. So I would like to ask these questions: 1. where are this motors sold? can they be sold in any place where car parts are sold? like GM or FORD, Auto Zone, or any other of those? 2. Is it too expensive to get this motor? 3. Is the electric generator sold in any "Auto Zone" or place like that? and I guess that's it. I would really appreciate help and answers.
