A video published to YouTube Sunday shows a group of Russians use an RPG-7 to fire an anti-tank rocket at 45 sheets of bulletproof glass.
"We did a 45-ply 400 mm thick bulletproof glass, to see whether it can withstand a shot from a bazooka," the individuals wrote on YouTube, according to an online translation.
The footage reveals the rocket has no trouble piercing through the bulletproof glass. Footage taken in the aftermath shows a hole where the rocket collided with the glass.
Video of the experiment started gaining traction on Reddit Monday night. At the time of publication, the video had amassed more than 100,000 views on YouTube.
