For those who love a bubbling, smoking cauldron or a rolling fog to help decorate their doorstep every October 31st, there are thousands of other uses for what fires that Halloween mood in today’s world. That little bit of magic and eeriness that causes that distinct look and feel is what is known as dry ice.
Dry ice is the solid form of carbon dioxide gas. At a temperature of -109.2F (-78.5C), carbon dioxide will sublimate (make the transition from gas to solid) at Earth’s atmospheric pressure. It is colorless, odorless, and is a non-flammable material. However, dry ice is realized at an extremely cold temperature, so it must be handled with the proper protection equipment to avoid frostbite.
Dry ice has many practical applications in today’s consumer, business, medical, and industrial worlds which can greatly aid in getting the jobs done that you face every day.

As long as the dry ice does not touch the flowers and keeps the air cool, they will arrive without wilting.
