Dry ice dispenser
This is such an ingenious idea and simple design that we’re left wondering why it’s not available in the US or anywhere else except Japan. If you purchased ice cream at a grocery store before, you definitely know why dry ice dispensers are a good idea.
By the time you get home, your store-bought ice cream has already melted, and your cold soda has gone lukewarm and flat. If you had the option to pick up a couple of ounces of dry ice, you wouldn’t have to worry about any of these things. Dry ice lasts up to five hours outside of a cooler, giving you plenty of time to make it home and place your ice cream in the freezer.
