How to Make Goop from Laundry Detergent

By Judith Bourassa Joy

Goop is the common name for a fun, gooey toy that you can bounce, stretch, squish and even break. Goop is actually a rubbery polymer that is easy to make at home with Borax (a laundry detergent booster), glue and water. You can make plain white Goop, or use food coloring or paint to make colored Goop. Although Goop will harden if you leave it out, you can save it in an airtight container and use it again and again.

Lay down a plastic tablecloth to protect your work surface.

Pour 8 ounces of white glue and 1 cup of water into the first mixing bowl. Add a few drops of food coloring or tempera paint if you want colored Goop. Mix well with a spoon.

Pour 1 cup of very hot water into the second bowl. Add 1 1/2 tsp Borax, and stir with the other spoon until most of the powder has dissolved.

Pour the Borax solution slowly into the glue mixture while stirring.

Stir the Goop for another two minutes.

Take out the Goop and knead it on the working surface until it is smooth and stretchy.


Store your Goop in an airtight plastic bag or container if you want to use it again. Otherwise, it will dry out and harden.


Do not give Goop to young children who may put it in their mouths.

Avoid getting Goop in your eyes or mouth.

Wash your hands when you're done with your Goop.

Avoid getting Goop on clothing or textiles—it can stain.

Clean up spills right away—Goop hardens and can be difficult to remove from carpets and other surfaces.
