How does a pressure cooker bomb explode?
A pressure cooker bomb, like the one used in Boston [and New York City in Sept 2016], takes the rapidly-expanding gasses in a typical gunpowder explosion and holds them under tighter atmospheric pressure. The resulting rupture is far more violent than if the gunpowder was placed in a non-pressurized container.
How long does it take for a dry ice bomb to explode?
30 seconds to 30 minutes
Bombs typically rupture within 30 seconds to 30 minutes, dependent largely on the temperature of the air outside the bottle. A dry ice bomb may develop frost on its exterior prior to explosion.
What happens if you put dry ice in a pressure cooker?
It can also result in a lot more violent splashing of the water as the CO2 sublimates, possibly icing over the regulator port. Instead, put the dry ice and water in a small plastic bowl, and put that in the bottom of the pressure cooker. Just don’t put it so close to the CO2 that it ends up freezing!
How much pressure builds up in a pressure cooker?
When you cook in a regular pot at atmospheric pressure (14.7 pounds per square inch [psi]), water boils at 100°C (212°F). Inside a pressure cooker, the pressure can increase by an additional 15 psi, to almost 30 psi.
Why do pressure cookers make good bombs?
When a bomber uses a pressure cooker, they’ll fill it up with shrapnel, ball bearings, or various other deadly items that will fly out post-explosion. Pipe bombs also can’t hold much in the way of shrapnel—nails, BBs, ball bearings—but a pressure cooker makes it easier to carry and conceal such lethal add-ons.
How much pressure does dry ice create?
Yes. The triple point of carbon dioxide is at 5.1 atmospheres, or 517kPa. This is why dry ice sublimates directly into a gas at atmospheric pressure. In order to obtain the liquid phase, we must have a pressure of at least that much.
