By the end of this guide, you’ll be a certified slime expert whipping up crazy neon slimes, glitter slimes, and fluffy slimes in no time.

Gather the Ingredients to Make Slime

To make slime, you’ll need just a few basic ingredients.

  • Glue (white school glue or PVA glue): This is the main ingredient that provides the sticky base for your slime. Elmer’s glue and Gorilla glue are popular brands.
  • Water: You’ll need about an equal amount of water as glue. Use room temperature water for the best results.
  • Borax powder (sodium borate): This is the key ingredient that turns the glue and water mixture into slime. You’ll only need about a teaspoon of borax powder for every cup of glue used.
  • Food coloring (optional): Add a few drops of food coloring to your slime for fun colors. Red, blue, and green are popular shades.
  • Extras (optional): Glitter, sequins, beads, styrofoam balls. Add extras to your slime for decorative effects.

Once you have your ingredients, it’s time to make the slime! Mix the glue, water, and food coloring together in a bowl. In a separate container, dissolve the borax powder in some warm water. Add the borax solution to the glue mixture 1 tablespoon at a time, stirring continuously, until the slime becomes stringy. Knead the slime with your hands until it’s the perfect slimy consistency! If it’s too sticky, add a bit more borax. If it’s too firm, add a splash of water.

Play with your slime by stretching, bouncing, and squishing it. Store any leftover slime in an airtight container. Borax can irritate the skin, so wash your hands thoroughly when you’re done playing. Now go make some slime and unleash your inner mad scientist!

Mix the Glue, Water and Borax Solution

Okay, you’ve gathered the ingredients, now it’s time to make the slime!

  1. In a bowl, combine 4 ounces of white school glue (like Elmer’s) and 1/2 cup of warm water. Mix well until combined.
  2. In a separate container, combine 1 teaspoon of borax powder and 1 cup of warm water. Stir to dissolve the borax and make a solution.
  3. Add the borax solution to the glue mixture 1 tablespoon at a time. Stir slowly after each addition until the slime becomes difficult to stir. This usually takes around 3 to 4 tablespoons of the borax solution.
  4. Remove the slime from the bowl and knead it with your hands. If it’s still sticky, add a bit more of the borax solution. If it’s too stiff, add a little more warm water. Keep adjusting until you get the perfect stretchy consistency.
  5. Knead and stretch your slime with your hands. It may be a little sticky at first, but will become less tacky as you play. Add slime activator powder, lotion, or clay to make it smoother and less sticky.
  6. Store your slime in an airtight container or ziplock bag. This will prevent it from drying out and keep it fresh for weeks.

Slime is meant to be a fun, creative experience. Don’t get too caught up in precise measurements – you can always add more borax solution or water to adjust the consistency. The key is to go slowly, be patient, and have fun with it! Stretch, squish, bounce and enjoy your awesome slime creation.

Add Food Coloring (Optional)

Add color to your slime

Now that you have your slime base made, it’s time for the fun part—adding color! Food coloring is an easy way to transform your slime into any shade you like. You can find food coloring at most grocery stores in the baking aisle. Liquid or gel food colorings work the best for coloring slime.

For a vibrant color, use 5 to 10 drops of food coloring for every 1/2 cup of slime. Add the drops one at a time, mixing thoroughly after each drop, until you achieve your desired hue. Keep in mind that the color may darken slightly as the slime sits. You can always add more color, but you can’t take it away, so go slowly.

Some tips for coloring slime:

  • Mix colors to make custom shades. For example, combine red and blue food coloring to make purple slime. Yellow and blue make green. Red and yellow make orange. The possibilities are endless!
  • Consider adding a second contrasting color for a swirled effect. Gently fold the second color into portions of the slime.
  • Metallic slime can be made by adding gold or silver glitter, or mica powder along with the food coloring.
  • Neon or bright slime is fun to make by choosing neon food colorings like neon pink, green, yellow or orange.
  • Pastel slime can be achieved by adding just 1 or 2 drops of food coloring at a time until you reach your desired soft shade.
  • Black slime can be tricky to make dark enough. You may need up to 1/2 bottle of black food coloring for every cup of slime. Add drops slowly while mixing to avoid ending up with gray slime!
  • Glow in the dark slime can be made by mixing in glow powder, available at many craft stores. Follow the directions on the product to determine how much to add to your slime.

By adding food coloring, you can transform a simple slime base into a colorful creation. Have fun with it and be creative—the possibilities for customizing slime are endless!

Knead the Slime With Your Hands

Once you’ve mixed the ingredients together, it’s time to knead the slime with your hands to achieve the perfect sticky, squishy consistency.

Add Activator Solution Gradually

Add the activator solution (borax and water) 1 tablespoon at a time. Stir thoroughly after each addition until the slime starts to form. You want the slime to get thick and sticky, but still pliable. If it gets too stiff, just add a bit of warm water and knead it in.

  • Keep mixing and kneading the slime with your hands until it’s the perfect consistency. This usually takes 3 to 5 minutes of play.
  • Push, pull, and squeeze the slime through your fingers. Fold it over on itself repeatedly.
  • If the slime is still sticky, just sprinkle in a tiny bit of borax powder or water and knead it in.
  • Knead in some food coloring or glitter now if desired.

Aerate the Slime

Once the slime is the right consistency, spend a few minutes stretching, pulling, and aerating it with your hands.

  • Roll the slime into balls or long strings and then roll it back into itself.
  • Lift parts of the slime up and fold it over, twisting and turning it.
  • Pull the slime slowly and gently to stretch it out, then fold it back.
  • Squeeze and release the slime in your hands.

Aerating the slime will make it softer, smoother, and more pliable. It also helps remove any trapped air bubbles. Play with your slime as much as you want – the more you knead and stretch it, the better the texture will become.

Your slime is now ready for hours of squeezing, stretching, and slapping fun. Store any leftover slime in an airtight container or bag. Enjoy your new squishy, slimy creation!

FAQ: Troubleshooting Your Slime

Why is my slime too sticky?

If your slime is sticking to your hands and everything else, it likely has too much activator. Add a bit more glue to balance it out. Start by adding 1 teaspoon of glue at a time, kneading it into the slime with your hands, until it’s less sticky. You can always add more activator to thicken it up again, but you can’t take it out once it’s added!

Why isn’t my slime slimy enough?

Slime that isn’t gooey probably needs more activator. Add borax solution 1 teaspoon at a time, kneading thoroughly after each addition, until your slime reaches the desired consistency. For slime that’s too thick, add a bit of warm water 1 teaspoon at a time. The heat will help loosen up the slime and make it slimier.

Why did my slime dry out?

If your slime dried out, it’s because it was left exposed to air for too long. Slime will dry out within 1-2 days when left uncovered. To prevent this, store your slime in an airtight container or ziplock bag. You can also add a moist paper towel to the container which will help keep the slime hydrated.

To rehydrate dried out slime, add warm water 1 teaspoon at a time, kneading it into the slime with your hands until it’s soft and gooey again. You may need to add a tiny bit of borax solution to help the water incorporate. Keep kneading and adding water slowly until your slime is revived!

Why does my slime have lumps?

Lumpy slime means the ingredients weren’t mixed properly. Add warm water 1 teaspoon at a time to help soften the slime, then knead vigorously with your hands. Pull and stretch the slime in all directions to evenly distribute the ingredients. You can also try microwaving the slime in short 10 second bursts, kneading in between, until the lumps disappear. Be very careful removing the slime from the microwave as the container will be hot!

With some TLC and troubleshooting, you’ll get your slime back to the perfect sticky, gooey, lumpy-free consistency. Don’t get discouraged if it takes a few tries. Making slime is a fun experiment, even when things go awry!


So there you have it, your very own slimy creation. Now that you’ve seen how easy it is to make slime at home, you can get creative and customize your slime by adding glitter, food coloring, foam beads, or whatever else you like. Kids will have a blast playing with slime and making different textures and colors. Adults, don’t be afraid to join in on the fun too! Slime is a great sensory toy for all ages.
