Watch this, and while you're watching don't think "omg how did he do that", just enjoy some really simple effects you can do with some really simple objects.
Don't ask here how any of them are done (that's why I put this in the public section :P), but instead think "how would I do that trick"?
all 40 are very simple tricks that you should be able to figure out SOME method for (even if it's not the one he used)
This type of thinking process will help you learn how to develop methods for your own tricks!
Enjoy :)
