Survive a Riot Quiz
Crowd dynamics, tear gas, and avoiding the wrong place at the wrong time
Crowd dynamics, tear gas, and avoiding the wrong place at the wrong time
In a crowd of 4+ people per square meter, you can no longer freely choose where to walk — and crowd waves can apply 600+ pounds of force on a single body. With 50 questions on crowd-crush mechanics, tear gas response, protest safety gear, and historical crowd disasters, this quiz separates crowd science from crowd myths.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll learn the physics of crowd crush, when crowd density becomes lethal, how to move through a dangerous crowd, what tear gas actually does and how to mitigate it, historical crowd disasters, riot control methods, and how to stay safe before, during, and after civil unrest.
Crowd crush (compressive asphyxia) occurs when a crowd becomes so densely packed that people cannot breathe. It is distinct from trampling — victims are crushed by pressure from surrounding bodies, often while still standing. It can happen in crowds even when no one is panicking.
Move uphill and upwind from the gas source immediately. Do not rub your eyes. Flush with large amounts of water or saline. Remove contact lenses as they trap chemicals. An N95 mask reduces inhalation but does not protect eyes — swimming goggles over an N95 provide better protection.
Crowd safety researchers consider 4 people per square meter to be the threshold where free movement becomes restricted. At 6+ people per square meter conditions become dangerous, and at 8-9 per square meter crowd crush and compressive asphyxia become potentially fatal.
