In case you didn’t know this, the term “smokescreen” isn’t a metaphor that describes a trick used to hide someone’s real intentions. In fact, this is an actual tactic that’s used to hide military units’ movements.

In the following video, recorded in 1923, you will see a plane that was dropping tetrachloride, creating a white curtain to hide ships. The substance is a yellow, corrosive, non-flammable liquid that hydrolyzed when contacting damp air. The result is dense white smoke made of droplets of titanium oxychloride and hydrochloric acid. This smoke is unbreathable for humans, requiring a respirator and goggles when humans are in close proximity to it.
These curtains were widely used during World War II. The curtain in this video looks nearly 100% solid like an iceberg, prevent either side from seeing what’s going on behind the curtain.
The Second World War, or World War II, was a global war lasting for six years between 1939 and 1945. The war involved many countries across the globe, including those with great powers divided into 2 opposing military alliances: the Axis and the Allies. In total, World War II involved over 100 million people from over 30 countries, costing them the entire economy, industry, and scientific capabilities. It resulted in 70-85 million deaths, tens of millions of whom died from genocides, starvation, disease, and massacres.
