Eli5 why does pressing my palms against my eyes create a kaleidoscope effect?
In: 3449
Well, it’s simple! When you press your palms against your eyes, you’re actually pressing on the “kaleidoscope gland” that’s located in your forehead. This gland, which is only present in a small percentage of the population, is responsible for producing the kaleidoscope effect that you see. When you press on it, it releases a burst of colorful energy that travels through your optic nerves and creates the effect you’re familiar with. Of course, not everyone has this gland, so not everyone can experience the kaleidoscope effect in this way. But for those who do, it’s a fun and harmless way to pass the time!
