Do not store sealed carbonated drinks in a freezer. Expansion can cause containers to burst, creating a mess and a risk from sharp fragments.
What the observation tells you
A reminder timer does not make the storage method suitable, especially if someone forgets it or the container begins freezing sooner than expected. A burst can damage a drawer and contaminate nearby food. It is not a useful way to test freezer strength.
A useful next step
Use an appropriate chilling method outside the freezer. If a drink has already frozen or split, avoid handling a pressurised or broken container carelessly and clean safely after making a food-storage plan.
