How Bulletproof is NeeDoh?

Published on October 9, 2025
Duration: 13:13

This video tests the ballistic resistance of NeeDoh stress balls against various firearm calibers, from .22LR up to .50 BMG. The presenter, from Demolition Ranch, demonstrates how the squishy material behaves like a non-Newtonian fluid, hardening under impact but ultimately failing to stop larger calibers. High-speed footage reveals projectile disintegration and energy transfer.

Quick Summary

NeeDoh stress balls exhibit non-Newtonian properties, hardening under rapid impact. While they can stop smaller handgun rounds like 9mm FMJ by absorbing energy, they fail against rifle calibers such as 5.56x45mm and .50 BMG, which cause them to disintegrate.

Frequently Asked Questions

What are NeeDoh stress balls made of and how do they react to impact?

NeeDoh stress balls are filled with a sticky, glue-like substance that exhibits non-Newtonian properties. This means they are soft and squishy under normal handling but harden significantly when subjected to rapid force, such as a bullet impact.

Can NeeDoh stress balls stop bullets from firearms?

NeeDoh stress balls can stop smaller caliber handgun rounds like 9mm FMJ, effectively absorbing their energy. However, they fail to stop rifle calibers such as 5.56x45mm, 300 Blackout, 6.5 Creedmoor, and .50 BMG, which cause them to disintegrate.

What calibers were tested against NeeDoh stress balls in the video?

The video tested NeeDoh stress balls against a range of calibers, starting with .22 Long Rifle, then progressing to 9mm Luger, .45 ACP, 5.56x45mm, 300 Blackout, 6.5 Creedmoor, and finally .50 BMG.

How did the 5.56x45mm round affect the NeeDoh stress balls?

The 5.56x45mm round caused significant fragmentation and disintegration of the NeeDoh stress balls upon impact. High-speed footage suggested the projectile itself may have exploded on contact with the material.
