A CRT is a very fast beam tracing device. One tiny ray traces horizontal lines across the screen, top to bottom. Depending on the speed, one should be able to see a band of brightness. That band of brightness relates to the shutter speed, and the width of that band of brightness relates to the curtain speeds (the width is constant with same curtain speeds). Very easy to do, on just needs a CRT television for that. If you a search online, you will get some pages that show this procedure with explanatory photos.
