What's the worst thing to do with a pressure cooker?

In terms of bad stuff happening from pressure cookers, the Boston Marathon bombing comes to mind. They made bombs using pressure cookers and killed and injured many people.

FWIW modern pressure cookers aren’t your grand-parents’ and are much much much safer. They’re awesome to cook stuff for a fraction of the time and energy you’d need using conventional cooking methods, they can sterilize stuff, and make preserves quicker.

Modern ones have thick bodies unlikely to ruptured, run at less than 2 atmospheres (I think 1.3?), have a pin that comes up when pressurized so you can’t open it until it’s fully depressurized, and a safety grommet that will shoot up and depressurize the cooker should the rocker’s exhaust be clogged.

Disappointing that the two most intriguing links (the spud cannon and the aluminum foil/draino video) are both dead.

Otherwise - fascinating!

I'm not sure why this posted, getting traction on 4chan somewhere?

The XKCD did come out 6 days before the Boston bombings.

Inspire, at a crazy guess actually inspired the Boston bombings since they had actual instructions to make a pressure cooker bomb to kill Americans.

I always wondered why Inspire chose the pressure cooker, it was in the article making bombs in your moms kitchen.

But would it work better than a normal pot?

Or was it chosen because it seems scary, which is why XKCD also choose it.
