How to Make Water Slime (With Glue + Special Activator)

A Crystal-Clear Slime Recipe That’s Cold, Jiggly, and Fun to Play With

How Do You Make Water Slime?

To make water slime, mix ½ cup of clear glue with 3½ cups of water. Prepare an activator using 1 cup of water mixed with 2 tablespoons of borax powder—this is key, as regular slime activators won't work. Stir everything together and place it in the fridge for 3 hours. Once chilled, your clear, wobbly water slime is ready to play with.

➣ 3½ cups of water

⚗️ For the Activator:

➣ 1 cup of warm water

➣ 2 tablespoons of this borax powder

➣ Food coloring or glitter for fun effects - check out Hemway Turquoise Holographic Mix.

➣ A sealed container for storage

Step-by-Step Instructions

➣ Mix Glue and Water In a large bowl, combine ½ cup of clear glue with 3½ cups of water. Stir well until fully blended.

➣ Prepare the Activator In a separate container, mix 1 cup of warm water with 1 teaspoon of borax powder. Stir until the powder is fully dissolved. This mixture is your slime activator.

➣ Combine Slowly add the activator to your glue mixture, stirring continuously. The slime will begin to form right away. Keep mixing until it thickens and pulls away from the bowl.

➣ Chill Place your finished slime in a sealed container and refrigerate it for 3 hours. This helps it firm up and gives it that cool, “watery” texture. If you have a lot of bubbles in your slime leave if for a few days and it will come out clear.

➣ Play! Once chilled, take out your slime and enjoy. It should be stretchy, clear, and cold—just like water slime should be!

Why This Activator Matters

This slime recipe only works with a strong, homemade borax activator. Off-the-shelf activators may be too weak to set the glue-water mixture properly. The high water content makes this recipe different from regular slime—so using the correct activator is essential for success.

Storage Tips

➣ Store your water slime in an airtight container in the fridge to keep it fresh.

➣ It can last for weeka if stored properly.

➣ If it starts to get cloudy or sticky, it’s time to make a fresh batch.

Safety Note

This recipe contains borax, which should be handled with care. It’s safe for older children with supervision but not recommended for toddlers or children who may put slime in their mouths. Always wash hands after playing with slime.

Frequently Asked Questions

Q: Can I use white glue instead of clear glue? A: No. Clear glue is essential for that watery, translucent effect.

Q: Can I skip the fridge step? A: Chilling the slime gives it the water-like feel and helps it firm up. Skipping this step will result in a runnier texture.

Q: Can I double the recipe? A: Yes, just maintain the same ratios for the glue, water, and activator.

Q: Is borax safe? A: In small, diluted amounts and with proper supervision, borax is generally safe for crafting. However, always store it out of reach of young children and avoid ingestion.
