Amazing Ooze (for younger children who might be tempted to taste it) Items Needed 1 cup cornstarch 1-2 drops food coloring (optional) 1/2 cup water Cover your work area well with newspapers. Put the cornstarch in a large bowl. Add 1 or 2 drops of food coloring if you want to color it. Add the water slowly, mixing the cornstarch until all of the powder is wet. Keep adding more water until this mixture looks like a liquid when you stir it slowly. The ooze is just right when it won't splash out of the bowl. Tap lightly on the surface with your finger or spoon. If it is too wet add more cornstarch, if it is too dry, add more water. Try to pick up the resulting "liquid". It should feel like a solid until you open your hand and then it will slip through your fingers
