Do not seal dry ice into a container except as detailed below,
because an explosive bursting of the container can result.
Dry ice, being frozen CO2 gas, can be used to carbonate water to
create sparkling water. Place some drinking water in a glass, and
add some dry ice. Allow it to bubble. Water ice may form around the
dry ice. If this happens you can either leave it alone, or break it
up with a spoon to help the process along. When all of the dry ice
is gone, taste the water that remains. It should taste slightly
carbonated. Coke haha
