How to make Coloured Slime

Slime is the new big thing among kids and adult alike. It’s just so satisfying to squish and stretch. The problem is, many slime recipes call for borax, a laundry additive. While we’ve never encountered any issues with borax, some people have reported burns from this type of slime. Others are concerned about how safe this ingredient is for a children’s toy. It may also irritate sensitive skin. You can also use this as a sensory experiment for kids that need tactile and visual stimulation. I got an alternative that is safer for kids – contact lens saline solution!

There are lots of recipes for slime. Which one you choose depends on the ingredients you have and the type of slime you want. This is a simple, reliable recipe that produces classic slime.


(NOTE: This is for a large batch. You can divide the amounts by 3 and make a smaller batch, especially if you want to test the recipe first. The contact solution binds the ingredients together.)

How to Make Colorful Slime

  1. Pour 12 ounces of glue into a container to mix your slime in.
  2. Add 1 1/2 tablespoons of baking soda. Mix together.
  3. Add drops of washable glitter paint. This won’t stain your hand as food colouring will! Mix together again. You can even add more glitter if you’d like. It says inside the slime!
  4. Add 2 tablespoons of saline solution.
  5. Mix the saline solution into your slime until it starts to form together


PLEASE NOTE: Adult supervision is recommended for this activity. Although contact lens saline solution is a safer option than Borax, it does still contain Boric Acid, and should not be ingested.
