Here are some fun bath concoctions. They are one of my roomate Tonya's many contributions to guerilla sociology...

Bath Bombs

Baking soda 1.5 cups
Citric acid (available at drugstores) 0.5 cup
Fragrance oil 1.5 tsp
Food colouring
Water in a spray bottle

Combine baking soda and citric acid in a small bowl. Add fragrance oil and food colouring and mix well. Spray surface of mixture with water until dampened. Keep spraying and mixing until mixture begins to clump. Form balls with hands or scoop into balls or press firmly into moulds. Release onto wax paper covered baking sheet. Let dry for at least 8 hours. (note: the key to this recipe is to add very little water and start forming balls early on- if you have cookie cutters you make bombs in fun shapes).

Milk Bath

Skim milk powder 2 cups
Baking soda 0.5 cup
Cornstarch 1 Tbsp
Fragrance oil

Mix all ingredients together and store in a container with a tight fitting lid.
