Science Buddies: "Ask an Expert"

I'm looking for help with my optical illusion science fair project. Is there any extensive advice you can give to me?
thanks.
sincerely,
Hopelessly confused.

Hi orginialeae,

Welcome to Science Buddies! We're happy to help with your project. However I think we'll need more information as to what you're thinking. What kind of experiment are you planning? What kind of question do you want to ask about optical illusions? Actually, we can even start with: what do you mean by "optical illusion"?

If you don't have the answers yet, don't worry - that's exactly the kind of thing we can help with as well. I just wanted to gauge what you're thinking. Please let us know absolutely anything you have thought about your potential project, from ideas to questions to potential barriers. We can work off of that.
