I have been thinking quite a bit about the material that magicians use. Sure we have seen effects like cups and balls, and clinking things, and egg bag used over and over again... but why? Is it because they are classics (or we have been TOLD they are)? Is it because we someone else do it and think, "Hey he got a good response from that, I bet I could too."? Perhaps they are just readily available from YFD. (if you don't know what that means, GTFO of magic.)
I think these are all contributing factors, but a big part of it is we know they are always there to fall back on. We know them, we know they work (Even if a metric fuckton of people have seen them), and they are readily available. The above tricks are just a smattering of the number of effects that have been flogged to death like 6 card repeat at a magic club meeting. I know a few of my readers do these tricks and do them well. Good for you. However, have you ever considered what you might create if you put these implements of ease down and tried to... create something new?
If you know that you will always have certain effects to "fill time", you will resort to them.
Just something to chew on...
