In fact, in 30 degrees, the cake still looks like an hour. I just took DQ cake (600g+4 pieces of dry ice) on September 18 last year and took the bus to school for more than an hour to share it with my classmates. He is still fine, showing no signs of melting, but I ate it as soon as I got to school, and I don't know how long I can last.

If you are afraid of melting too fast, it will be better to ask the clerk to give you more dry ice. The rest can't really help you, so why don't you take a taxi?

DQ seems to be out of ice cream cakes.

In addition, you can buy it near the place where your girlfriend meets. Generally, there are DQ and Haagen-Dazs in any prosperous place.
