technostronomy on Instagram: "The iodine clock experiment is a classic chemistry demonstration that shows how the rate of a chemical reaction can be controlled and observed. It's called a "clock" because after mixing a few clear solutions, there's a predictable amount of time before the mixture suddenly and dramatically changes to a dark blue or black color.

MEMEZAR • MEMES & MEME-CULTURE on Instagram: "Give him that Oscar right now! Some snakes play dead as a defense mechanism to avoid predators. When threatened, they may flip onto their backs, open their mouths, stick out their tongues, or even emit foul smells to appear lifeless and unappealing. This behavior tricks predators that prefer live prey into losing interest and leaving. Once the danger passes, the snake quickly “comes back to life” and slithers away to safety.
