How the Slushy Cup actually works
Read this once and you will know everything you need to.
The four steps
Freeze the cup once, then turn any cold drink into slush whenever you feel like one.
-
Freeze the cup
Pop the empty cup in the freezer for four to six hours. Overnight is easiest.
-
Pour in any cold drink
Juice, lemonade, iced coffee, soda. If it is cold, it works.
-
Squeeze for about a minute
Give it a steady squeeze. You will feel it turn to slush in your hands.
-
Rinse and refreeze
Hand wash only. Back in the freezer, ready for the next round.
Drinks that slush well
Juice
Any brand. Orange, apple, mango, berry.
Lemonade and sodas
Sugar is what gives slush its soft texture. Sugar-free and diet drinks set hard rather than slushy, so stir in a spoonful of sugar if you want to use them.
Iced coffee and iced tea
Chill first. Sweetened tastes better as slush.
Sports drinks
Great after a run. Cold and slushy.
What not to pour
Nothing hot, and never freeze the cup with a drink already in it. It goes in empty. Milk and oat milk both work well, just not milk that is close to its date.
Keep it working for years
Hand wash only
Warm water and mild soap. No dishwasher, no hot water.
Dry the outside before refreezing
A dry cup freezes faster and cleaner.
Freeze upright
It keeps the gel evenly distributed for the next round.
Something not right?
Freezing times, cleaning, shipping, returns. The answers we send most often, in one place.
It's not turning to slush.
Your cup probably was not frozen long enough. Give it a full overnight freeze and try again. If the drink is warm, chill it first.
Still flat after a full freeze? Walk through the freezing checks.
It leaks a little.
The lid must be lined up with the arrows on the cup. If it still leaks, do not fill above the top ring.
More on what makes a cup leak, and how to stop it.
The gel feels soft even after 6 hours.
Your freezer might be set too warm. Aim for −18°C or 0°F.
If the freezer is cold enough and it is still soft, these are the usual causes.
The cup is hard to squeeze.
A cup straight out of a very cold freezer needs a minute on the counter before the walls give. If it is still stiff, or it squeezes but nothing thickens, here is what to check.
