1 cup baking soda
3/4 cup citric acid crystals
3 Tbsp. cornstarch
1 small scoop (the one from baby powdered baby formula works great )
Small gift jar.
Mix ingredients and place in an airtight container. Keep salts dry, moisture will cause them to react and fizz. Sprinkle about 1/4 cup of the salts into warm tub of water. Yield: 2 cups. Just as much fun, as taking a bath in a bottle of champagne.
