Fast growing Ice Crystals

Dry ice is a great material to have in a shop that can be a workable stand in for liquid nitrogen in most cases. When left unattended for a couple minutes water in the air will freeze on the dry ice's surface and form a furry coating. After the dry ice has completely sublimated the water ice begins to warm up to room temperature and melts a few seconds later. Normally the water ice crystals are so small that they appear to be a uniform fur but putting a small grain of dry ice under the microscope shows how complex the growing crystals really are.
