It is generally not recommended to freeze carbonated drinks, including Kool-Aid Jammers, because the carbonation can cause the container to expand and potentially burst, leading to a messy and potentially dangerous situation. Freezing carbonated drinks can also cause the taste and texture to change, as the carbon dioxide gas can alter the drink's flavor and carbonation level.
If you still want to freeze a Kool-Aid Jammer, it is important to take some precautions to prevent the container from bursting. First, make sure the drink is stored in a freezer-safe container, such as a plastic bottle or freezer bag, with some room for expansion. Second, you can release some of the carbonation from the drink by opening the container, allowing some of the gas to escape before freezing it. Finally, it is recommended to freeze the drink for no more than 2 hours to prevent the container from bursting.
However, it's worth noting that freezing a Kool-Aid Jammer may not be the best idea, as the drink is primarily made up of water, sugar, and artificial flavors, and freezing can alter the taste and texture of the drink, making it less enjoyable to drink.
