Fizzy Bath Salts

Fizzy Bath Salts
Mix 1/2 cup baking soda
1/4 cup cornstarch
1/4 cup citric acid
10 drops fragrance oil
a few drops of food coloring if desired

Spritz of water

Mix ingredients together then stir with a spoon or your hand -- but be sure to use a glove if you do that.

Then lightly spritz with water until mixture just holds together when you squeeze it.
It will fizz. That is normal. Press into a mold. Really press hard to get a good impression. Place a piece of cardboard on top of the mold and invert. It should fall out. Leave undisturbed until hard.
