Humans can do any fool thing they put their mind to. Swallowing dry ice is one of the faster ways to end the story.
Dry ice is a trap – the moment it touches your mouth or your throat, kills everything, the cold is too much.
There is no burn but a mean freeze, very deep, shatters the cells of a body.
The tissue dies right there, black and brittle.
But the cold is the kinder of the two deaths it offers, there are worse things with dry ice.

There is trouble of gas-Some may be confused but dry ice is frozen gas – The gut is a warm and wet place, dry ice wakes it up with a roar, the gut expands, fast-A small piece becomes a huge bubble of pressure. There is nowhere to go – the blast will blow a hole proper through your stomach or your bowels, your insides rupture. A body cannot survive that, that is death. A thing of violent cold and pressure. A stupid way to learn your last lesson.
