The Freezing Chamber

The Slushy Cup has a built-in freezer unit with small fans that circulate cold air. Once you pour your favorite drink into the cup, the freezing chamber brings it down to the perfect slushy temperature, usually around 20-25°F. The fans help ensure it freezes evenly into tiny ice crystals.

Gather the Parts

First, lay out all the Slushy Cup parts in front of you:

  • Cup base
  • Rotating blade assembly
  • Lid
  • Slushy mix packets (your choice of flavor)
  • Bottle or pitcher of water

Assemble the Base

Take the cup base and rotating blade assembly and fit them together, twisting clockwise to lock in place. The blades should spin freely when assembled correctly.

Add the Water

Pour 3-4 cups of water into the base. For the best results, use chilled water. Room temperature water will produce slushies as well, but they may take longer to freeze.

Add the Mix

Tear open the slushy mix packets and pour the contents into the water. Use one packet for a lightly flavored slushy or two packets for an intensely flavored treat. Mix with a spoon until the powder is dissolved.

Attach the Lid

Put the lid onto the cup, fitting the opening over the rotating blade assembly. Push down firmly to seal the lid in place.

Freeze & Enjoy

Place the entire Slushy Cup in the freezer for 6-8 hours until completely frozen. Your slushy is ready to enjoy when it reaches your desired consistency. Simply remove from the freezer, peel off the lid and watch as the blades churn your frozen treat into a frosty delight! Use the built-in spoon to scoop out your slushy. Enjoy!

With a few basic steps, you’ll be enjoying a homemade slushy in no time. Simply adjust the amounts of mix and water to your taste for the perfect slushy every time.

Filling the Slushy Cup Properly

To get the perfect slushy consistency in your Slushy Cup, filling it properly is key.

Add ice and liquid

Start with 8-10 cubes of ice and 1 1/2 cups of your chosen slushy liquid like fruit juice, soda or an icy cocktail base. For an extra cold slushy, use frozen juice concentrate or chill the liquid in the fridge before adding. Pour the ice and liquid into your Slushy Cup.

Seal and shake

Put the lid on your Slushy Cup tightly and shake vigorously for 60-90 seconds. This helps the ice crush into small particles and incorporates air into the slushy for a light, frosty texture.

Check consistency

After shaking, check how slushy your drink has become by tilting the cup to see how the contents move. If it’s still very liquid, reseal and shake for 30 more seconds. Repeat until it reaches a thick, spoonable consistency. Be careful not to over-shake, or it can become too hard.

Re-shake as needed

Your Slushy Cup will stay cold for hours, but may become more liquidy over time as the ice melts. Simply re-seal and shake again for 30-60 seconds to restore the perfect slushy consistency. Add more ice cubes if too much has melted.

With some experimenting, you’ll be making the best slushies in no time. Keep trying different flavors and combinations in your Slushy Cup for an endless array of icy treats all summer long. Enjoy!

Tips for Using Your Slushy Cup

To get the most out of your Slushy Cup, you need to follow some tips:

  • Make sure to fill your Slushy Cup with a chilled liquid before freezing. For the best results, use a liquid that has been refrigerated for at least 2 hours. The colder the liquid, the faster it will freeze into a slushy treat.
  • For an extra icy slushy, add a few ice cubes to the liquid before freezing the Slushy Cup. The ice cubes will increase the freezing temperature, resulting in a frosty delight.
  • Secure the lid tightly before placing the Slushy Cup in the freezer. This prevents air exposure and ensures an evenly frozen slushy.
  • For the perfect slushy consistency, freeze the Slushy Cup for 6 to 8 hours. Check on your slushy after 6 hours for a spoonable treat or up to 8 hours for a firmer icy snack.
  • When ready to enjoy, remove the Slushy Cup from the freezer and shake or stir thoroughly. The slushy may become separated in the freezer, so mixing it up will provide an evenly distributed icy drink.
  • Add extras to your slushy like fresh or frozen fruit, chocolate or caramel syrup, whipped cream or marshmallows. Customize your slushy for a variety of flavor combinations.
  • Rinse and dry your Slushy Cup after each use and avoid the dishwasher which can cause damage. Hand wash the lid and base separately to prevent warping. Allow all parts to fully air dry before storing.

Following these useful tips will ensure you get the most out of your Slushy Cup and enjoy frosty treats all summer long. Mix and match flavors for a cool and refreshing experience. Your Slushy Cup will be a hit at any party, BBQ or camping trip.

Making Slushies With the Slushy Cup

Making your own slushies at home is easy with the Slushy Cup. Just follow these simple steps:

Add ice and flavoring

Fill the Slushy Cup about 2/3 full with ice cubes. Add your choice of flavoring – fruit juice, soda or a pre-made slushy mix. For juice, use a ratio of 3 parts juice to 1 part water. For soda, use it straight or diluted with a little water. Slushy mixes should be prepared according to package directions.

Seal and shake

Put the lid on the Slushy Cup and seal tightly. Shake vigorously for 1 to 2 minutes until the ice is crushed and the mixture is slushy. The longer you shake, the slushier it will get.


Remove the lid and spoon the slushy into glasses. Top with whipped cream or sherbet if desired. Your homemade slushies are ready to enjoy!

The Slushy Cup uses a simple but effective mechanism to make slushies at home. The airtight seal and the motion of shaking causes the temperature to drop through a process called adiabatic cooling.

This causes the ice to crush into small granules that give slushies their characteristic icy, slushy texture. With some ice, your choice of flavoring and a few minutes of shaking, you’ll be enjoying slushies just like from your favorite convenience store or movie theater.
