Storm in a Glass

Work up a storm inside your house! You only need ingredients you have at home to get started.

--WHAT YOU'LL NEED--

Shaving cream
A large glass
water
Food coloring
A spoon

--STEP 1--

Fill the glass 1/2 full with water

--STEP 2--

Spray some shaving cream on top of the water to fill the glass to ¾ full.

--STEP 3--

Use your finger or a spoon to spread the shaving cream evenly over the top of the water. The top of the shaving cream should be flat.

--STEP 4--

Mix ½-cup water with 10 drops of food coloring in a separate container. Gently add the colored water, spoonful by spoonful, to the top of the shaving cream. When it gets too heavy, watch it storm!
