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.

Technology on Instagram: "The iodine clock reaction, first discovered by Hans Heinrich Landolt in 1886, is a famous experiment that perfectly showcases chemical kinetics in action. ⚗️✨ When two clear solutions are mixed, the liquid stays colorless for a short time before suddenly turning deep blue. This dramatic shift highlights how reaction rates work — with factors like concentration and temperature directly influencing the speed of the reaction. It’s a classroom favorite because it turns abst

The Film Enthusiast on Instagram: "Sometimes silence speaks louder than words. In The Godfather Part II (1974), Michael (Al Pacino) and Kay (Diane Keaton) lock eyes for nearly a minute, no dialogue, no music before he wordlessly shuts her out.
