Directions for Giving: On Valentines Day give someone you love your bath fizzy. I suggest a mom type person; and, oh, how happy she will be if you washed out the tub for her and maybe the rest of the bathroom too! Mom’s love that stuff!
When you give Mom, or someone you love, their bath fizzy, ask them to notice the ingredient card and explain to them the purpose of each ingredient. Be sure to use the word surfactant and explain what a surfactant is.
Make a card to go along with your gift. It is to be filled out by the recipient of your bath fizzy.
