These refreshing bath bombs masquerade as ice cream, but you won’t need a freezer to make or store them. The baking soda and citric acid react when they hit water to produce a fizzy, great-smelling bath. Instead of the standard-issue gift basket, carefully wash out an empty ice-cream container, line with tissue paper, and place bath bombs inside (bonus Plenty points for reuse!).
1 ½ cups baking soda
½ cup powdered citric acid (a natural product often used in preserving fruits and vegetables or in making sprouted foods; ask your local health-food or vitamin store if they carry it)
2 ½ tsp almond oil or apricot kernel oil
1 Tbsp water
10 to 15 drops fragrance oil or essential oil
5 drops natural food coloring (optional)
1. Combine dry ingredients in a large glass or ceramic bowl. Stir until well mixed.
2. Slowly add almond oil and stir until dry ingredients are moistened. Add fragrance oil and food coloring (if using) and stir until well mixed. Add water a few drops at a time until the mixture holds together without crumbling.
3. Roll the mixture into two-inch balls by hand, or portion out individual “servings” with an ice cream scoop for an authentic “freezer-fresh” look.
4. Place the scoops on a sheet of wax paper and leave them to dry until hardened (may take up to several days).
To use: Add one bomb to running water in the bathtub.
