How Breathalyzers Work: Science Behind Alcohol Detection

🧠 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

Invention on Instagram: "An electromagnetic coil accelerator, uses magnetic fields to propel objects at high speeds without the need for chemical propellants. The system works by running electric current through a series of coils which generate pulses of magnetism. As the projectile moves forward, each coil activates in sequence, pulling it further down the barrel until it exits at remarkable velocity. The underlying principle is simple, but the engineering required to synchronize the magnetic p
