I had no idea a pressure cooker bomb with normal fireworks gunpowder could be that powerful.

I bet a lot of people did not know that either.

I am more worried about copy cats now.

1. I've known since my first copy of the Anarchist's Cookbook

back in the early 1970s. Early pressure cookers without relief valves can be a bit more powerful but they all work.

Fortunately, I lack ambition. So do 99.9% of would be copycats.

However, i can see a lot of survivalist types loading the bunker up with them. I hope TSA is keeping an eye on sales of multiple cookers on Amazon.

2. Used in a firework

the components, which we wont go into here, when formed into gases have freedom of release. Used elsewhere they dont have that freedom. There is only a narrow difference between a homemade canon and a pipe bomb - less than a millemeter.

3. When did you first learn about pressure cooker bombs?

4. I could tell you a story

About a young boy and his sister, an old percussion shotgun with one blown out nipple, some firecrackers, a roll of toy gun caps, cotton balls and a handful of BB's. And a pissed off grandfather.

But I'm the only survivor of this incident and I'm not about to reveal all the details. Suffice it to say there was lots of noise, fire and some very frightened chickens.
