What Dippin Dots have in Common with the Covid-19 Vaccine
Remember Dippin Dots? Those weird little dots of ice cream that come in a cup at places like stadiums and shopping malls? Well as it turns out, Dippin Dots have to be stored at -49*F.
Although the Covid-19 Vaccines have to be stored at similarly sub-zero frigid temps, the method of moving Dippin Dots around the country is the same for the vaccines. It's done with dry ice. The dry ice has to be replaced every 5 days in the supply chain while the vaccines are stored and transported. It's dangerous to handle the dry ice, both because it can cause burns on skin and also because the evaporating carbon dioxide takes up space where air would otherwise be.
Popular Science has an article about the supply chains for the Covid-19 vaccines and also Dippin Dots:
