How to take a picture with a soda can.

Very cool.

Hmm. In the video, the paper was exposed to light before loading into the camera obscura, therefore ant image would be totally black !
He'd need to "load" the "camera" in darkroom conditions.

Many years ago, a fellow club member's kid was given a class project to make a photo with a pinhole camera using a cardboard oatmeal cylinder carton. I was asked to advise as I was the Kodak employee member. As students had permission to deviate from the supplied container, I used a yellow box with black interior 3"x 3"x 2" commonly used to hold small parts and accessories by Kodak. I advised him to use a match to briefly flash the smallest pinhole he could make, the quick flame burns off any residual fuzz from the puncture. I gave him several cut to fit pieces of print paper for testing. As kids will, he elected to make only one exposure. The class rule was the pinhole camera must be brought to class taped sealed and the result would be discovered in class. Our student elected to make an over night exposure in his dad's workroom with ambient light, taking it to school the next morning. The result of a 6+ hour exposure with low light gave a print that looked as if it were a daylight shot, and with very surprising sharpness showing objects on the bench with readable labels.
