Looking for some advice on the topic of storing dry ice for an extended period of days. In our current production there is a small sight gag every night of a classic "misty frothy beverage mug". Every night we are only using a small amount of dry ice, but we find that we are purchasing more dry ice every second or third day because it is sublimating so fast. The cost of this is starting to add up and I know there has to be a better way than just putting the dry ice in a lunch cooler and into the freezer, which is what they are doing now.
I know their exist purpose built dry ice containers, but those are unfortunately outside the range of our budget. What are the most successful methods employed in the storage of dry ice?
