Could A Briefcase Bomb Have Changed The Course Of WWII? | MythBusters

In this episode of MythBusters, Adam and Jamie explore whether a briefcase bomb could have successfully assassinated Hitler by testing the impact of an explosion in an enclosed bunker versus an open room, ultimately demonstrating that the change of venue significantly reduced the bomb's lethality. They also investigate the myth that you can slap sense into someone, finding that a slap can indeed enhance focus under certain impairments.

Could A Briefcase Bomb Have Changed The Course Of WWII? | MythBusters

Key takeaways

The briefcase bomb intended to assassinate Hitler failed primarily due to a last-minute change of venue from a fortified bunker to an open room, significantly reducing its lethality.
Testing revealed that an explosion in a closed space can produce a pressure wave up to 4 times more lethal than in an open space, confirming the conventional wisdom surrounding the assassination attempt.
The myth that you can slap sense into someone was explored, with studies showing that a slap can stimulate the fight-or-flight response, potentially enhancing focus and decision-making under certain conditions.
The MythBusters utilized scientific methods, including pressure transducers, to measure the impact of blasts in different settings, showcasing the importance of empirical evidence in debunking myths.
Consider the environment when planning any explosive or high-impact event, as the venue can drastically affect outcomes, as demonstrated in the Hitler assassination attempt.
If faced with a stressful situation, explore methods to enhance focus, such as brief physical stimuli, but ensure they are safe and appropriate for the context.

High-Level Overview

This episode of MythBusters explores the famous assassination attempt on Adolf Hitler during World War II in 1944, specifically testing the myth that Hitler survived a briefcase bomb only because the meeting venue was changed from a sealed underground bunker to an above-ground room with open windows. The hosts recreate both settings at scale and full scale to measure the lethal effect of the explosion in each environment. Additionally, the episode investigates a secondary myth: whether a slap to the face can restore alertness and cognitive function to an impaired person. The investigation blends historical research, scientific experimentation, and human behavioral testing, providing insights into blast physics and human physiology under stress.
