Unique/scary/interesting demonstration speech topic?

[ghost]

Okay, I don't perfer "normal" demonstration speech topics like "How to fix your hair" or "How to make this recipe," instead, I want something interesting, strange or freakish to demonstrate that doesn't involve a weapon--can you guys help me?

BTW, this is for my COM 105 class, so please help me if ya can by making a list of subjects and how'd the topic is relevant to the class.

Ummm, listing the abbreviation and number of the class doesn't help anyone. I'm assuming it's a communications class...

Hmm. If you wanted to do something cool, you could demonstrate how to do some scar stage makeup. Or maybe show how to do this trick: http://www.youtube.com/watch?v=OBXkH8oIHkc
