The USSR could identify fake Soviet passports because the metal staples wouldn't rust. (Their real passports used very low quality metal that corroded very quickly.)
The 12-foot Chrysler Air Raid Sirens placed around the US during this time were so powerful that they could turn fog into rain!
At one point, the US considered dropping over-sized condoms on the USSR that were labeled "medium." The apparent intention was to demoralize the enemy.
Russian officials thought the building in the center of the Pentagon was a secret meeting room. In reality, it was a hot dog stand!
Canada relocated Inuit in the Arctic in order to assert control of the region. (The USSR was very interested in the Northwest Passage.)
The USSR and the US almost had a joint space program, but after Kennedy was assassinated, the plan fell through. Why? The Soviets didn't trust President Johnson.
The term "Cold War" was coined by George Orwell in his book "Animal Farm." For those of you who don't know, "Animal Farm" is a book that pokes fun at Stalinism.
In an attempt to ease tensions between the USSR and the West, 18-year-old German pilot Mathias Rust flew through Soviet defenses and landed in the Red Square.

The Tsar Bomba is the largest nuclear weapon to ever be detonated. The Soviets performed the detonation in the arctic and the cloud rose to 7 times the height of Mount Everest!

A Korean Boeing 747 (flight 007) was shot down in 1983 for accidentally crossing into Soviet airspace. This prompted the US to make GPS technology publicly available.
When the CIA noticed soccer fields in Cuba, it became suspicious because "Russians play soccer, Cubans play baseball."
Both sides used propaganda quite heavily. Maps were even made with the specific intent of portraying the enemy as bigger and closer than it actually is.
The Soviet Union was (and Russia still is) known for operating "closed cities." Basically, these were entire cities where civilians were restricted from leaving.
The USSR is one of the few countries in history to have internal passports. Basically, you couldn't just go travel wherever you wanted. Today, Russians still use their internal passports as ID cards. (These are separate from their international passports.)
Soviet Colonel Stanislav Petrov was monitoring Soviet radar when it showed an all out nuclear attack by the US. He had a split second to respond and decided against firing back. Why? He suspected that it was a glitch. Fortunately, for the rest of us, he was right.
