Tricks that seem like real magic?

[Albert]

So I was wondering what tricks there were that really make people believe in what people call 'witchcraft'?

For example, things like biokinesis or pure smoke seem like real magic to people. I find that for card tricks, people sometimes tend to convince themselves as sleight-of-hand, which makes the magical aspect disappear from their mind.

Not things like a topit or the raven as they are really limited to smaller objects. Any ideas?
