Your Task
In groups of no more than two students, construct a bath bomb, prepare a product
information label, and package your product for sale.

Part I. Making the Bath Bomb

                           Equipment                      Che micals
                       100 mL beaker               Citric acid, 20 mL
                       250 mL beaker               Cornstarch, 20 mL
                       600 mL beaker               Ester fragrance, 1.0 mL
                       Glass stir rod              Baking soda, 65 mL
                       Plastic sandwich bag        Vegetable oil, 30 mL
Record the masses of each of the ingredients before making the bath bomb.

                Ingredients                                    Mass (+/- 0.1 g)

1. Mass each of the dry ingredients using the 250 mL beaker.
2. Mass the vegetable oil and the ester for fragrance using the small beaker.
3. Pour all ingredients into the large beaker and mix carefully with the glass stir rod. Take
   care not to break the stir rod!
4. Form the mixture into the shape of your choice. Place the bath bomb in a plastic
   sandwich bag and take home to dry and package. At home remove the bath bomb from
   the plastic and allow to dry for 24 to 48 hours before packaging.
5. Package the bath bomb as if it were a consumer product. Keep in mind that the bath
   bomb is brittle and an airtight seal will prevent the fragrance from escaping over time.

Part II. Pre paring the Product Information Label
Prepare a product information label which lists all of the ingredients, from highest to lowest
concentration by percent mass (%w/w). Use appropriate IUPAC naming systems for the
baking soda and ester ingredients.

Part III. Package Your Product for Sale
This is your opportunity to create an attractive product as if it were to be available for sale.
Be creative and consider who you may sell to, where your product may appear, how your
product will be manufactured and shipped, and how you wish it to be displayed in a store.
