Search around and find examples of sensation and perception interact. We're looking for something like an illusion. It could be optical (there are tons of these), but a hearing one (or touch, taste, smell) would be great if you can find one because it'll set you apart.

1. Get your illusion to Coach Crump: either by photocopy, email, flashdrive, URL link, whatever.
2. Explain in your own words how or why this illusion works.
