Dry ice is not just regular ice, it is special! Dry ice is the solid or frozen form of Carbon Dioxide. This means that the gas called Carbon Dioxide was frozen in sub-zero temperatures. It is almost 5 times colder than water ice! Dry ice can result in serious frostbite, so wear hand protection while handling this. Dry ice can be used for lots of things. It can be used for keeping things like food cold on long hikes. It is also used for special effects like smog machines. This happens by putting the dry ice in a bucket of hot water. This causes a smoke like material to rise into the air. This is actually the Carbon Dioxide vaporizing. This is also going to be used in the transport of the COVID-19 vaccine.
