I'm new so please be patient with all my questions and comments. So to make replies easier I'll just number all of my questions

1.) My biggest stutter with my spectators is when they say something to the effect of: "Lemme see you other hand", "Can you do it again?", "Can I see your prop" I don't know how to politely answer them no, without giving up the trick itself. Examples: They always want to see my other hand during a Vanishing trick, Some tricks I can't do again without preparation (Self Tie'in Shoestring) others (Levatations) I don't want to do more than twice, and they want to see the cups (Cups'N'Balls) before I repeat the process. How do you kindly say they're a one-time bang?
2.) This guy does a trick I would like to learn how to do: http://www.expertvillage.com/video/1433 ... -trick.htm Ok, here are my thoughts on how it's done and why: The first time I watched this (when I began learning) I was amazed and never payed attention to his hand that doesn't move much, like he plans for. As I watched the clip over and over, the best thing I can guess is (about 1:17 into the clip) he drops his right hand under the table a little while the left distracts the audience. I assume that is where the Beta was grabbed. Now if you look closely (about 1:40) when he pours out the fish, his hand is dry (thus he doesn't grab into a bowl for the fish) also when the fish comes out of the hand so does a little bit of water. So my overall conclusion goes: The fish is prepared before he ever starts the show. The fish is actually kept in a small glass/plastic vile/bag and hung on the back edge of the podium. When it is time for the trick he can grab the vile (1:17) then pours the fish out along with the water from the vile (1:40) then he drops the vile right after the fish is in the water. Any ideas?
3.) On this trick http://www.expertvillage.com/video/1432 ... -trick.htm I assume the ball is in the bag the whole time, thus it has to be unfolded the whole time. In the back, which he never reveals, there is a slit/hole cut to let his hand freely hold whatever he needs (ball) to make it seem like nothing is in there. Correct? Ideas?
4.) I'm not trying to burst anyones bubble, but being new I just assume, when Chris Angel does his tricks does he use the camera to his advantage? Or something that allows him to do these tricks? Here are some examples: http://www.youtube.com/watch?v=ZlIwcVAxZsU, http://www.youtube.com/watch?v=7r0M2JCOco0, http://www.youtube.com/watch?v=u7gl8nNs ... re=related I understand if no one wants to reveal how he does it, because they are amazing tricks. The reason I ask because there are also links that "reveal" him.
