Making goo can be a fun activity for kids of all ages. Goo can be colored and used for Halloween or parties. The goo can also be used for interesting science experiments focusing on the different states of matter: liquid, solid and gas. Using simple ingredients in the recipe, goo can be easily made with the help of small children. Sensory skills can be heightened and art projects can be created playing with goo.

Step 2

Measure 1 cup of cornstarch. Keep the measuring cup level and add to the bowl. Combine contents of the bowl evenly.


Step 3

Measure out 1/2 cup room temperature water. Slowly add water 1/8 cup at a time to thedry ingredients. Adding too much water to the mixture will result in a watery substance rather than goo.

Step 4

Mix all ingredients in the bowl with your hands until the desired consistency is reached. Add more water if necessary. Color the goo using a few drops of food coloring for an extra touch.

Step 5

Distribute goo evenly to small bowls for students or children. Provide paper towel for any mess that is created.


Goo can be drizzled on paper to create unique designs and art.
