Dry ice is basically solid carbon dioxide.

The surface temperature of a dry ice block
is about -78 degrees Celsius or -109 degrees Fahrenheit.

This means it is much cooler than ordinary
ice which is made up of water.

If dry ice comes in contact with our skin,
our cells begin to freeze and die within seconds.

In addition to this, storing dry ice in airtight
containers can be dangerous.

This is because dry ice sublimates, i.e. it directly gets converted from solid state to gaseous state.

Hence, in airtight containers, the gas produced can build up.

Exert pressure on the walls of container which can lead to a dangerous explosion.
