Can LEGO’s Really Stop a Bullet? Simulation Reveals How Many of them are Required!
Have you ever wondered how many LEGO pieces would be needed to stop a bullet? It’s a strange question, but now we have an answer thanks to a fascinating simulation.
The Simulation
A YouTube video by Zachdfilms takes a deep dive into this fun thought experiment, showing how various projectiles interact with stacks of LEGO pieces. The simulation tests three types of projectiles: a 9mm round, a .45 caliber round, and a high-speed rifle round. The results might surprise you.

Results of the Test
The simulation shows how the pieces perform when hit by each of these projectiles:
- 9mm Round: A stack of 22 pieces is enough to stop a 9mm round.
- .45 Caliber Round: This slightly slower but heavier round requires 28 pieces to halt its force.
- High-Speed Rifle Round: The powerful rifle round needs 60 pieces to prevent it from passing through.
Social Media Reactions
Naturally, the results sparked a lot of curious and funny reactions on social media:
- One person joked, Let me really quickly stack 100 pieces for full safety.
- Another cheekily added, Bank robbers about to start wearing armor now.
- A third commenter quipped, So hypothetically, 62 LEGO pieces would make me unstoppable.
It’s clear that people found the idea of LEGO armor both amusing and intriguing.

A Reminder About Safety
While the LEGO simulation is an entertaining thought experiment, it’s important to remember that real-world safety should never be taken lightly. In another video, the creator demonstrates the consequences of putting a finger in the barrel of a firearm. Contrary to popular belief, this would not stop the projectile—instead, it would likely cause serious injury.
In conclusion, while stacking LEGO pieces might give you some temporary amusement, it’s always essential to approach safety with care and responsibility!
