Instructables

How can I create Magical special effects?

I have been cast as Merlin in a medieval fair living chess board act. We have a few reliable magic tricks we've used in the past, but I'm trying to find/think up new ideas. This is a live show and I will most likely be standing on an elevated stage for most of it. I don't mind cheesy tricks (I might even do the string of handkerchiefs up the sleeve gag). Illusions that can be used in "combat" are very welcome. So, if you have ideas, or know of any websites that will help, I'd really appreciate. I've looked through Instructables, but haven't found much, so if you know any good ones, assume I missed them.

Flash paper and a match.
Smoke bomb on a stick.
Sparklers on a stick.
Can of silly string up your sleave.

It's all show from the sounds of it, keep it simple but "visual"
