How to Make Green Slime (a Children's Craft Project)

During the long days of summer break this recipe for green slime is simple enough for older children to make by themselves, while providing a few hours of entertainment. Once the project has been completed, the slime can be kept in an airtight plastic container or plastic bag for several weeks of gooey fun and pranks.

Things You'll Need

  • Spoon For Stirring
  • 2 Mixing Bowls
  • Green And Yellow Food Coloring
  • 1 Tablespoon Borax
  • Plastic Bag Or Clean Plastic-Covered Container
  • 8 Ounces Of Glue

Combine 1 cup of cold water with 8 ounces of glue in a medium mixing bowl.

Combine 1 tablespoon of Borax powder with 1/2 cup of hot water in a second bowl. Keep stirring until the Borax has dissolved.


Add about 10 drops of green food coloring and 10 drops of yellow food coloring to the Borax mixture.


Gradually add the hot Borax mixture to the glue-water mixture and stir about 30 seconds.


Mix the ingredients thoroughly. In less than a minute, you'll have a gooey, non-sticky, stretchy slime.


Store your slime in a plastic bag or airtight plastic container. The goop can keep for several weeks if placed in the refrigerator between uses.
