Equipment

  • Measuring cups and spoons
  • Spoon for stirring

Ingredients

Instructions

  • Start by making a borax solution. To a medium sized bowl measure out and add a cup of warm water and 1 tablespoon of borax. 
    Stir this mixture until it’s dissolved and set it aside. 
  • The second solution is the glue mixture and it's made in a large mixing bowl. In this bowl you’re going to start with a half cup of warm water and a whole cup of glue. 
  • To this mixture go ahead and add a half teaspoon of baking soda. Now I just want to reminder you of the difference between baking soda and baking powder. It’s baking soda that we use in this recipe.
  • I added a few drops of food coloring to my mixture (mine was a gel but liquid food coloring works too). Part of my glue was a glitter glue, which already had a little bit of blue food coloring in it, but I went ahead and added more blue food coloring.
    At this point, you could add other things to your solution as well. I would’ve added glitter to it if I had it. I have it somewhere in my “stash” but just couldn’t find it. Sad face.
  • Mix these ingredients up together and then add 2 Tablespoons of saline solution (which is a slime activator- activating a chemical reaction).
  • So in this step of making the easy fluffy slime recipe, you will notice that the ingredients interact and it begins to thicken and pull away from the sides of the bowl as you stir.
  • Now I think that you will sometimes find that you don’t need to add anything more to the mixture. It will just start setting up and that’s all you need to do. But my slime was still sticky.
    So at this point in time I added one tablespoon of the borax solution to the glue mixture in the large bowl. Then it began to set up even more. It pulled away from the bowl and you can see it’s ready to be handled.
  • I put a bit of the saline solution on my hands and then picked up the slime.
    So I played around with it for a while and began to knead it. And as I kneaded the slime it firmed up more and more, so it was less sticky and easy to handle. 
    Mine probably got even a little bit too stiff by the end, I would have liked stretchier slime. Perhaps I got a bit too much contact solution on my hands. But it had such a fluffy consistency and I had so much fun playing with it and pulling on it.
  • Your slime will last a number of days if you keep it in an airtight container.

Notes

Tip: Use Elmer's white glue or other brand of white glue to make the fluffiest slime. 
Note: I’m going to tell you the recipe that I used, but I do suggest cutting this recipe in half if only using it for one child to play with. It was a really large recipe!
Go to the post to read a bit about the science side of this recipe- why two liquid ingredients mix to make slime.

Safety precautions- 

    • Use this recipe with older children.
    • It is important to keep young kids and pets away from borax. Be sure to throw all extra borax solution away when done. 
    • Shaving foam can burn your eyes so don't touch or rub your eyes while handling. 
    • It would be a good idea to wear gloves if you have sensitive skin. I had no problems, but others may. Also food coloring can put color on your skin.
    • Lastly, work over a table or flat surface as I'm guessing that slime would stick in carpet.
