The Devastation Pressure Cooker Bombs Can Unleash is Terrifying

It could have been a disaster. A pressure cooker bomb, like the ones used at the 2013 Boston Marathon, inspired another evil plot, the Feds say.

The two suspects are 28-year-old Noelle Velentzas of Queens, New York, and her 31-year-old ex-roommate, Asia Siddiqui.

The FBI says the women called themselves "Citizens of the Islamic State" and "real bad bitches."

What was their alleged target? A police funeral.

They allegedly got the idea after seeing thousands of cops turn out last December to honor two NYPD officers who were assassinated as they sat in their patrol car.   

How much damage could a bomb made by a regular pressure cooker cause?

A device similar to what the accused terrorists were planning to use was built by bomb experts from New Mexico Tech.

VP for research Van Romero explained the devastating effects of flying shrapnel to INSIDE EDITION producer Daela Cetrone.

He said, "It's not likely to kill a lot of people, if you are very close to it you will obviously be killed, but it will throw fragments a long way."

We won't tell you how the bomb is made, our interest here is explaining why it can be so devastating.
We set up cameras behind protective shields to record the explosion, then head for shelter in this bunker, about a quarter of a mile away.

There was a deafening explosion rocked the desert and bits of shrapnel flew in all directions. A charred pot and a bent lid are all that's left of our pressure cooker bomb but somehow, the plywood walls surrounding the bomb remain intact. Why?

Romero said, "Everything shot straight up. More than likely what happened in Boston, the bomb was placed on its side and it shot out in the street."

Now imagine a bomb like that aimed at police officers attending a funeral for one of their own.

The two women have been charged with conspiring to detonate a bomb. They could face life in prison if convicted.
