Frequently Asked Questions

How many LEGO walls did it take to stop a 9mm bullet?

In the experiment, it took exactly 5 LEGO walls, each approximately 1.25 inches thick, to stop a 9mm FMJ bullet fired from a Glock 17. This resulted in a total penetration depth of about 6.25 inches of LEGO material.

What firearm and ammunition were used in the LEGO ballistic test?

The test utilized a Glock 17 handgun chambered in 9mm Luger. The ammunition fired was 115-grain Full Metal Jacket (FMJ) 9mm rounds, commonly used for target practice and self-defense.

What was the total thickness of LEGO needed to stop the bullet?

With each of the 5 LEGO walls measuring approximately 1.25 inches thick, the total thickness of LEGO material required to stop the 9mm bullet was about 6.25 inches. This demonstrates the material's surprising resistance.

Did the 9mm bullet penetrate the LEGO structure completely?

No, the 9mm bullet did not penetrate completely. It successfully stopped after penetrating 5 layers of LEGO bricks, indicating that the interlocking plastic structure provided sufficient resistance to halt the projectile.
