There were many things Ron did not know. Things he would never understand about Harry and Hermione, who were raised by Muggles. Like the Internet. Or how hairspray works without magic. Or rubber ducks!
But there are some things he's sure he's gotten a right grasp on. One of the first was tellyphones. He's figured it out!
"You know that thing you were telling me about," he began one night in the common room. Hermione and Harry both looked at Ron. "The Muggle stuff you put in your tellies and mobiles? What do you call it?"
"What are you on about?" Hermione asked. Harry looked just as confused as she.
"You harnessed the spirits of the sky. Beings born from thunderstorms. Static from the heavens. You trapped lightning in a bottle and use to talk to each other from all over the world." His eyes took on a mad kind of glint like he'd peeled back the Veil and could now understand the inner machinations of the universe.
"You- You mean electricity?!" realized Harry. A smile stretched his lips. He couldn't believe what he was hearing. Around him, in the dusk-lit common room, his fellow Gryffindors surround Ron and listened in awe.
"We all know Thunderbirds run across the clouds, and where they step rain falls, and lighting zaps, and thunder booms." Ron began again. "But these Muggles, see, found out a way to capture the lightning. Then they use it to connect the tellyphones and their tellies and radios. They use them in hair blowers, which make hot air come out so they can dry their hair after they shower. And I used to think that the tellies were prisons where they put you if you broke the law, but no-"
Seamus and Dean, who sat shoulder-to-shoulder nearby, were both struggling to keep in laughter. When Harry and Hermione looked at them, it was all the four of them could do to not erupt into uncontainable guffaws. Ron spoke louder thus:
"They sit you in front of a camera, but not just any camera! A camera that records what's called video - which is like our moving pictures! But without magic, without potions, just with this electricity!"
"How does that work?" someone asked.
"They call it 'science'."
"What's that?" another asked, curious.
"Beats me."
McGonagall came in in her tartan gown to quell the noise, for there was a clamoring to know more of these absurd Muggle not-magics." Everyone was speaking over one another and she needed to shout a number of times before they ceased.
She sent them to bed, but not before asking, "Is it true there are countless communities beholden to sending one another images of cats?"
