No need for funky stuff, just do the classic (lol) Young's slits experiment which should be more than enough oddness for anyone.
I was shown it at school, using microscope glass slides that we waved over a Bunsen burner running cold, to coat with soot. We then carefully etched parallel lines with a compass by hand. Our (~17 y/o) efforts were a bit random but we did get some smudgy banding results on the screen.
- ambicapter 22d agoUsing a compass is interesting, use two razor blades taped together is much easier and it’s close enough to perfect parallel lines.
- gerdesj 20d agoIt was the '80s so safety razor blades were available but in a posh public school (UK version) aged ~17, compasses were everywhere and large old style razor blades were not - the modern style razor with one or two thin blades was a thing. We could have probably got some needles from matron for a finer point, than a compass. Your pair of razor blades is a great solution.
