Why do older TVs have a weird screen effect while being viewed on another camera? | because the refresh rate of the TV screen collides with the frame rate of the video resulting in an "animation" of said refresh rate - the line moving up or down the screen.

Did those Duracell batteries with the little "press here to see power remaining" function actually work? If so, how? | They did.

If images are just data that says what color each pixel should be on screen, then why are some bigger in size than others? | Compression.

Why aren't things like Caffeine or Nicotine Scheduled (controlled) substances? | I think it's not controlled in this way because caffeine and nicotine in themselves are not harmful and extremely difficult to overdose on in their "natural" form.
