Dry ice is not a liquid form Andy. It is a solid and one unique fact about it is carbon dioxide goes directly from a solid phase to a gas with no liquid phase in between. Because of the drastic difference in volume when going from a solid to a gas carbon dioxide can potentially be an extremely dangerous material if not handled properly. It must never be sealed tightly in a container or pressure can build up. With pressure comes heat and with heat comes even faster and violent expansion. By definition an explosion involves the rapid expansion of a gas. Trust me I found out the hard way when a plastic container filled with dry ice blew up like a bomb in a fraction of a second. Dry ice is fine if handled correctly. Just make sure it's vented properly or you'll be in for one heck of a big surprise.
