The device had a yield of 9 kilotons — similar to the Hiroshima bomb — but this time, the detonation occurred beneath the ocean’s surface. Within a second, a dome of water rose over 840 feet into the air. By seven seconds, it had widened to nearly 3,800 feet, sending violent plumes in every direction. By the 12th second, the vertical column began to collapse, while massive water surges co

🧠 on Instagram: "The iodine clock reaction, discovered by Hans Heinrich Landolt in 1886, is a classic experiment that vividly demonstrates chemical kinetics. It involves a sudden color change from colorless to blue, illustrating the concept of reaction rates. This reaction occurs when two clear solutions are mixed, with one stage of the reaction taking longer, leading to a delayed color change. Widely used in classrooms, the iodine clock reaction offers a hands-on way to explore the factors inf
