The digest

This detailed exploration tests five widely circulated myths to determine their validity using scientific methods and experimental setups. It addresses misconceptions about explosive toilets, dangerous gasoline vapors, medieval barrel traps, premature burial survivability, and the lethality of falling pennies. The findings provide clarity on each myth’s feasibility, making this briefing valuable for professionals interested in safety, physics, and investigative science.

1. Exploding Toilet Myth: Can Smoking Near Flammable Liquids in a Toilet Cause an Explosion? (00:01–07:30)

The myth involves a person pouring flammable liquids (bug spray, gasoline, hairspray) into a toilet, followed by someone lighting a cigarette near the bowl, causing an explosion.

Setup: The team sourced a deep toilet bowl for optimal vapor containment, utilized a crash test dummy to simulate a human, and built a Lexan blast chamber to contain any explosions safely.
Tests with Various Fuels: Attempted ignition with hairspray, bug spray, butane, gasoline, and gunpowder.
Findings:
Hairspray and bug spray created minor ignition “poofs” but no explosion strong enough to cause harm.
Gasoline flames ignited but failed to produce a concussive blast; the cigarette was generally extinguished by the liquid rather than igniting it explosively.
Gunpowder caused a strong blast but failed to dislodge or injure the dummy seriously.
Conclusion: While some flammable vapors can ignite with a flame, none created an explosive force sufficient to blow someone off the toilet. The myth is busted.
