A leaking slushy cup is almost always one of five things, and four of them take a minute to fix. Here is how to work out which one you have.
First, check it is actually leaking
Take the cup out of the freezer and stand it on a dry towel for ten minutes without touching it. If the towel is damp but the cup is still full, that is condensation, not a leak. A frozen cup pulls moisture out of the air and it runs down the sides.
This is the most common false alarm. If the level inside has actually dropped, keep reading.
1. The lid is not seated properly
Take the lid off and put it back on slowly. It should sit flat with no gap anywhere around the rim. If one side lifts, something is caught in the thread. A drop of dried juice is enough to break the seal.
Rinse the rim and the inside of the lid under warm water, dry both, and try again.
2. You filled it too high
Liquid expands as it freezes. Fill past the line and it has nowhere to go, so it pushes out around the lid and the straw hole.
Fill to about three quarters and leave room at the top. If you are unsure, pour in less than you think you need. You can top it up after the first squeeze.
3. It is coming out of the straw hole
This looks like a leak but it is pressure. When you squeeze, the slush has to go somewhere, and the straw hole is the easiest way out.
Put the straw in before you squeeze, and squeeze slower. Short presses work better than one hard push.
4. The cup was washed in hot water or a dishwasher
Dishwashers run hot enough to warp the lid and the seal. Once the seal is out of shape, the lid will never sit flat again and it will leak every time.
Hand wash only, in cool or warm water. Dry it, then put it back in the freezer.
5. The inner lining is damaged
This is the real failure, and it is rare. The cooling layer sits between the two walls of the cup. If it splits, you will see liquid coming from the body of the cup rather than the lid, and the cup will also stop freezing properly.
Three things cause it: dropping the cup while it is frozen, washing it in hot water, or freezing a drink with a lot of alcohol in it. Alcohol never fully freezes, so it stays liquid and moves around inside.
A damaged lining cannot be repaired.
