Frozen Tea

I am going to the Expo with my friends next Wednesday. Since it is going to be really hot, someone recommended bring frozen bottles of tea to stay cool. At the same time, she said that regular plastic bottles would crack when frozen, so we should buy tea in bottles that are made to be frozen. Today, I went to a supermarket to look for one, but I couldn’t find any in the frozen food section. When I was about to give up, I spotted the frozen tea next to an ice cream section. Interestingly, it looked like the frozen teas were the most popular item at the freezer section.
