How Bulletproof is a Solid Glass Ball?

Published on October 18, 2025
Duration: 15:02

This video tests the bulletproof capabilities of an 8-inch solid glass ball against various calibers, from .22 LR to .50 BMG. While smaller calibers only chip the surface, larger rifle rounds cause significant shattering. Surprisingly, even when shattered, the glass fragments effectively stopped projectiles from reaching a dummy placed behind it, demonstrating an unexpected level of protection.

Quick Summary

A solid glass ball demonstrates surprising ballistic resistance. While smaller calibers only chip the surface, larger rounds cause shattering. Even when broken, the glass fragments effectively stop bullets, preventing penetration.

Frequently Asked Questions

Can a solid glass ball stop bullets?

Yes, surprisingly, a solid glass ball can stop bullets from various calibers. While smaller rounds cause minimal damage, larger calibers cause shattering. Even when broken, the glass fragments effectively block projectiles from passing through.

What happens when a rifle caliber hits a solid glass ball?

When hit by rifle calibers like .223 or .308, a solid glass ball shatters significantly. However, the core fragments of the ball remain intact enough to stop the bullets, preventing them from penetrating further.

Is a solid glass ball a fire hazard?

Yes, a solid glass ball can be a fire hazard. Its spherical shape can magnify sunlight, similar to a lens, potentially igniting flammable materials like paper or fabric if left exposed.

What calibers were tested against the glass ball?

The test included small calibers (.22 LR, 9mm, .45 ACP), magnum calibers (.44 Magnum, .50 AE), rifle calibers (.223, .308), and heavy calibers (12-gauge slug, .50 BMG).
