Silicone oil, a seemingly ordinary chemical, played a huge role during World War II. At that time, the German army entered the Soviet Union and encountered a once-in-a-century cold winter. The lubricating oil inside the mechanical equipment froze, causing the mechanized troops to be paralyzed. Experts from the former Soviet Union discovered a magical substance - silicone oil, which has excellent antifreeze properties when mixed with oil. It was this discovery that enabled the former Soviet Union to gain a huge combat advantage on the battlefield and eventually defeated the German army.
