Things You'll Need
Rubber or vinyl gloves
Liquid measuring cup
Children typically enjoy playing with anything they can squeeze or spread around -- just observe a child playing in the mud and see the joy on his face to know this is true. It is very easy to make play goop at home with simple ingredients from your kitchen. The goop will be non-toxic, but will be pretty messy, so be prepared to have the child play with it in a contained area that you can easily clean.
Put on rubber or vinyl gloves. This is especially important if you are going to be using food coloring in the goop.
Place 1 cup of flour or cornstarch in a bowl. Add 1 drop of food coloring to the flour or cornstarch, if you are coloring your goop. Food coloring goes a long way, so start out with just 1 drop -- you can always add more coloring later.
Fill a liquid measuring cup with warm water. Slowly add the water while using a whisk or fork to blend it with the flour or cornstarch. Continue adding water until the goop is of the consistency you want.
Knead and mix the goop with your gloved hands. Add more food coloring and water at this time if necessary.
Goop made with flour will dry out and harden more quickly than goop made with cornstarch.
Food coloring will stain. Before letting your child play with goop containing food coloring, make sure he is wearing an apron or other clothing that you don’t mind getting stained. Cover play surfaces with newspaper or disposable plastic tablecloths.
