Any ice in parts of the basin exposed to sunlight would have evaporated and escaped into space.
You now have a CO2 "snake" that will grow as the dry ice evaporates, and if all goes well, will explode when the pressure gets high enough.
Add a chunk of dry ice and stir until the dry ice evaporates away.
Even ice evaporates.
This time she did not stir, but the ice gradually evaporated, then reformed on his body.
In the defrosting process, ices (clathrate) may partly migrate into the soil and partly may evaporate.
When the dry ice evaporated, it filled the canister with carbon dioxide and drove out any oxygen, thus preserving the body without refrigeration.
When dry ice evaporates, the temperature of the vapor is considerably lower than room temperature.
The ice was worn away-not melted, but sublimated: over the years the ice had evaporated without first turning to water.
Allow it to sit tightly covered for about three days until all the dry ice evaporates.
