According to this, floppy disks actually do filter for infra-red light, so that part makes sense. This site says that remote controls work by sending pulses of infra-red, like Morse code, so changing the focus of the beam seems irrelevant. Perhaps when the guy who made the video was playing around with the focus, he ended up moving the light on and off the sensor, in a way that corresponded with one of the codes. Turning the flashlight on and off would probably do the same thing.

wow tagged this as fake to begin with but its even better browsing comments and seeing so many people want to try it!
the only way two pieces of floppy could create different frequencies is if they were rotating and polarized light. and even that might not do it. and since they are stationary im assuming that the dude was suggesting that they filtered out everything but IR?
