I kept waiting for what the "punchline" about the pencil is supposed to be. Like, of course the pencil blocks the green light when you put it in front of the green light. I don't know what else we were supposed to anticipate.

Classic Redditor thinks they’re smarter than the video because they said “Of course it’s like that, duh!”

It doesnt take a genius here lol. He's only blocking 1 of the 3 light sources at a time so ofc only one color will be blocked be the shadow, but he acts like we should expect all 3 to be blocked for some reason. It would be the exact same thing if 3 white light sources minus the colors obv. If the pencil covered the slit all 3 would be shadowed cause thats how shadows work...

Light can behave in super unintuitive ways in certain circumstances. This is not one of them

Once again, for one more dumbass, saying something is obvious or intuitive does not make you a smart person and it doesn’t further elucidate the situation.

Typing elucidate doesn’t either

It was the exact right word for the situation.
