DIY Putty Slime Recipe for Kids

Making putty is an easy and fun science project to do at home with kids. Like making slime, you’re going to get a little messy and it will take a few minutes to get to the right consistency. Putty is more firm than slime and less sticky. We chose green for our diy putty recipe, but you can choose any color of the rainbow!


  • 4 oz. white glue
  • Green food coloring
  • 1/3 cup liquid starch
  • 2 T. Cornstarch

  1. Pour the glue into a bowl and add food coloring of your choice. Stir until blended to your desired color.
  2. Add 1/3 cup of liquid starch to the glue and begin mixing with your hands. Once thickened, begin folding the mixture onto itself.
  3. Add the cornstarch and continue folding the mixture onto itself until it reaches a putty like consistency. Add more cornstarch if the mixture is too slimy.

Store your putty in an air-tight container.

Putty S.T.E.A.M. Activities


  • Mixing the putty is a great visual example of liquids into solids.
  • Before making the putty have kids predict the outcome of mixing the ingredients together, observe what happens when the ingredients are mixed, and report on their findings.


  • Use the putty as the “glue” that holds together a toothpick structure.
  • Experiment with building a tower with round pieces of putty.


  • Combine different colors of food coloring to teach secondary colors while mixing the putty.
  • Create putty art with pieces flattened on a table. Make a solar system, trees, flowers, or have kids use their imagination to create art from putty pieces.


  • Separate the putty into pieces for addition or subtraction. Squish the putty together as a visual example of addition, and pull the putty apart for a visual example of subtraction.
  • Practice measurements while mixing the putty ingredients together.
