Cops say 22-year-old Pedro Ruiz held a book to his chest and persuaded his girlfriend, Monalisa Perez, to fire a gun at him from a foot away.

Ruiz thought the book would stop the bullet. Instead, it went straight through, killing him.

The gun was a .50-caliber Desert Eagle, the power of which was notoriously showcased in the Brad Pitt film Snatch.

Inside Edition went to Guns for Hire, a gun range in Midland Park, N.J., to reveal the sheer power of the weapon in question.

During the demonstration, two bullets ravaged a massive dictionary, emerging right out of the other side of the book.

The firearm is regarded as the most powerful handgun money can buy.

Cops say Ruiz and his 19-year-old girlfriend staged the stunt at their Minnesota home to lure more viewers to their YouTube channel.

They spoke about the channel in a video posted the same day he was killed.

“Imagine when we have 300,000 subscribers,” she said in a video.

She also expressed her doubts about participating in the stunt.

Three hours before the tragedy, she tweeted: "Me and Pedro are probably going to shoot one of the most dangerous videos ever. His idea not mine."

The tweet included two "worried face" emojis.

She is seven-months pregnant with the couple's second child and faces up to 10 years in prison on a charge of second-degree manslaughter.
