About 500 years BC, someone in China or Greece discovered the camera obscura technique. That means letting light from the outside shine through a small hole and thus projecting an image on the opposite wall. 2500 years later six students and one teacher in Hylte (also called stinky town) discovered that same wonder of physics. Great success! Not sure they got a better understanding of how a camera works from the experiment, but wow:ed they were, and me too.

stinky town projected onto a white board!
