Homemade slime recipes to make with grandkids

As a grandparent, you greatly value the time you get to spend with your grandchildren. 

Whether you're playing games, watching movies or just sitting and talking, you all benefit from your time together and the memories you're creating. While intergenerational bonding is important, it can also be a bit challenging - after all, your grandkids are growing up in a vastly different era than you did, and you don't exactly have all of the same interests. Sometimes, it's nice to be able to connect with them about things they like and find ways to involve yourself in some of their interests.

The latest craft craze could be just the thing for you to try together next. Homemade "slime" has recently been a huge hit in schools all across the country - so much so that craft stores are struggling to keep its key ingredients, like white school glue, in stock, according to Today. Kids create slime for its aesthetic appeal, and play with it by pulling it apart and reshaping it. 

It's a simple product to make that has numerous ways to customize it, so it's a fun, and somewhat messy, activity you can do together. And think of how cool you'll be when you help your grandkids craft their latest batch of trendy slime!

The basic slime recipe
This old standard recipe, as listed on Home Science Tools, has been a staple science classroom experiment for decades. With just four ingredients, which you may already have in the house, it's simple to make. If you're feeling fancy, customize it by adding glitter, scented essential oils or by mixing multiple colored slimes together for a tie-dye or ombre effect. 


  • 1 oz white school glue
  • 1/4 cup borax
  • 3-4 drops of food coloring
  • 1/4 cup water


  1. Lay out some newspaper or other disposable surface onto your table. Keep some wet paper towels handy to help clean up any residual slime from your hands. 
  2. In a mixing bowl, thoroughly combine glue, water and food coloring. 
  3. Add borax to the mixture and slowly stir it in. 
  4. Once it becomes too thick and tacky to mix with a utensil, start kneading it with your hands until it loses its stickiness. 
  5. Store in a sealed container when not in use. 

Borax-free slime recipe
In high concentrations, borax can irritate skin. As a result, some people try to make slime recipes that use alternative ingredients to prevent any accidents. This borax-free recipe listed by ABC News uses common contact solution instead. It can be customized the same way as the basic recipe by creating fun color combinations or adding accessories to it.


  • 1/2 Tbsp baking soda
  • 1 Tbsp contact lens solution
  • 4 oz white school glue
  • 3-4 drops of food coloring


  1. Combine glue and baking soda in a bowl.
  2. Once thoroughly mixed, stir in the food coloring.
  3. Add the contact solution and mix until it begins to take on the slime consistency.
  4. Knead the slime with your hands when it becomes too hard to mix.
  5. If it remains too sticky no matter how much you knead, add an additional 1/4 Tbsp of contact lens solution.
  6. Store in a sealed container when not in use. 

Fluffy slime recipe
This variation of the recipe from CNET is also free of borax, and has a different consistency than traditional slime - it's airier and less sticky. Along with additions like glitter, you can also add polystyrene beads to create a new texture for this slime. 


  • 1/2 cup shampoo
  • 1/4 cup cornstarch 
  • 3-4 drops of food coloring
  • 6 Tbsp water


  1. Mix shampoo and cornstarch together in a bowl. 
  2. Once fully combined, add food coloring and mix until fully saturated.
  3. Add water, one tablespoon at a time, until thoroughly mixed.
  4. When not in use, store in a sealed container.

Glow-in-the-dark slime
This recipe from Science Notes takes a basic slime recipe but adds glow-in-the-dark paint for a fun, iridescent twist. 


  • 4 oz clear school glue
  • 1 cup plus 1/2 cup warm water
  • 3 oz glow-in-the-dark craft paint
  • 2 tsp borax.


  1. Stir glue and 1 cup water together until fully combined. 
  2. Mix in glow paint.
  3. In a separate bowl, combine 1/2 cup water with borax and mix until borax is mostly dissolved.
  4. Add borax mixture to glue mixture and stir or knead until fully combined.
  5. Shine light directly onto slime and then turn the light off to see it glow.
  6. Store in a sealed container when not in use.

Liquid glass slime
This crystal-clear slime takes on an interesting look. Replace clear glue with clear glitter glue for a blob of slime that really sparkles. Try this recipe from Instructables for your liquid glass slime.


  • 1/2 cup clear school glue
  • 1 cup plus 1/2 cup warm water
  • 1 tsp borax


  1. In one bowl, mix glue with 1/2 cup of water until thoroughly combined.
  2. In a separate bowl, mix remaining water with borax until dissolved.  
  3. Combine the glue mixture with the borax mixture and stir or knead until thoroughly incorporated. 
  4. Store in a sealed container when not in use. 

Magnetic slime
This scientific recipe from ThoughtCo requires some more unusual ingredients, but will make for a unique product that your grandkids may not have seen before. 


  • 1/4 cup liquid starch
  • 1/4 cup white school glue
  • 2 Tbsp iron oxide powder
  • Magnets


  1. Combine iron oxide powder with liquid starch and mix until smooth.
  2. Add glue and knead with your hands until fully combined.
  3. Use magnetic to make slime "dance," as well as playing with it as any ordinary slime.
  4. When not in use, store in a sealed container.
