I just wrote a demonstration speech for lucid dreaming a few months ago. But after taking the class I will definitely say that it is much better to do something that isn't so difficult to conceptualize. A speech about lucid dreaming is not good for people who have no clue what it is. My speech would have been ideal for beginners that are at least familiar that LDing exists My professor just didn't understand it. But she was an overweight ignorant bitch so she loved that all the girls in the class gave demos about how to bake something and they all brought in food. Great manipulation device, she really enjoyed stuffing her cake hole. I still got an A on it though at least.

So I would suggest NOT to do something like meditation. People might think you're crazy if you talk about reading palms, but if you don't care about that, more power to ya. Also if you are going to do a pendulum, you'd have to demonstrate how it works in the class so be prepared for it not to work properly. People are going to want to see you tell fortunes, and they'll be disappointed when you don't.
