These cups use a freezable inner liner to turn your cold drink into a slush. Here’s the general flow:

1. Freeze the cup (or inner core) until the cooling layer is completely solid.
2. Pour in a well-chilled beverage, leaving a little space at the top.
3. Squeeze the soft outer walls. Ice crystals form against the cold liner and mix into the drink.
4. Stir or scrape with the spoon-straw as you squeeze to build that slushy texture.

Many beverages can work, including juice, milk-based drinks, or flavored beverages. Carbonated drinks may foam, so pour slowly. Results can vary based on how cold your drink starts, the freezer’s temperature, and the drink’s sugar content.

Freeze it until the cooling layer is fully solid—many customers find doing this the day before they want a slushy is a convenient approach. Time can vary based on freezer temperature, cup size, and how full your freezer is.

• Place the cup near the back of the freezer for more consistent cold.
• Give the cup a gentle shake—if you don’t feel any liquid movement inside the walls, it’s usually ready.
• Between batches, return the cup to the freezer to re-chill.
• For model-specific guidance, check the care instructions in the item’s product details on Walmart.com.

Starting with a fully frozen cup helps the drink set up more quickly, but textures may still vary by beverage.

A few small tweaks can help the cup perform well, though results depend on your drink and environment.

• Use smaller pours and work in batches—less liquid chills faster.
• Squeeze from the bottom and sides in a steady rhythm to keep fresh liquid moving across the cold surface.
• Rotate and scrape with the spoon-straw so ice crystals mix evenly.
• Let carbonated drinks settle before squeezing to minimize foam.
• Very thick liquids or chunky add-ins may take longer; blend or strain if you prefer a smoother texture.

If the drink isn’t thickening, give the cup a short rest, then continue squeezing to encourage crystal formation.

The cup doesn’t add ingredients, so you can choose what goes in. If you’re aiming for less sugar, consider:

• Unsweetened or low-sugar beverages (e.g., flavored water or seltzer).
• Diluting juice with water to reduce overall sweetness.
• No-sugar-added drink mixes or light versions of your favorites.
• Natural flavor from pureed fruit or a splash of citrus.

Texture can vary with different sweeteners and flavorings, so you may need to experiment with ratios. Review nutrition labels to align with your goals. For personalized dietary guidance, it may be helpful to consult a qualified health professional.

Care can vary by item, so check the product’s instructions on Walmart.com. Many freezable cups benefit from gentle, simple cleaning.

• Hand-wash the cup, lid, and straw with mild soap and a soft sponge or bottle brush.
• Avoid abrasive scrubbers, boiling water, and microwaves.
• Rinse parts promptly after use, especially with dairy or fruit.
• Let everything air-dry completely before returning the cup to the freezer.
• Store upright in the freezer to limit odors; keep the lid and straw clean and dry.

If you need replacement lids or straws, availability can vary by seller—check the item page for compatible parts and options.
