A RECIPE for Fizzing Bath Oil Balls (makes about 25 pieces) A great and cheap Xmas gift1/4 cup baking soda 2 tablespoons citric acid or ascorbic acid (powdered vit C) 1 tablespoon borax powder (for softening) 2 tablespoons powdered sugar (for binding) 2 tablespoons sweet almond oil 1 teaspoon Vitamin E oil (preservative) 1/4 teaspoon fragrance or essential oil Combine dry ingredients in a bowl and stir until well blended. Drizzle in almond oil and stir until mixture is moistened. Add vit E oil and fragrance and stir until well mixed. Take teaspoon sized globs of mixture and form into ball shapes with fingers. (Mixture will be VERY crumbly and fragile, so do the best you can) Place the balls on a sheet of waxed paper and leave alone for 2-3 hours. After 2-3 hours, gently reshape the balls. Let the balls air-dry and harden for 10 days. Store balls in a closed container to protect from moisture. To use, drop a ball into bath water. Enjoy!
Citric acid would be both better & cheaper than ascorbic acid. You might have to mill the acids, as well as the borax, down to a fine powder first.
Bath Bombs 2 parts baking soda 1 part ascorbic or citric acid powder 1 part cornstarch Combine ingredients using a food processor if possible, can add colors and EO's. Be sure it's EO's and use a drop at a time as they have a strong scent. The trick is to bind the ingredients together with a little melted cocoa butter and slam them in a mould then into the freezer.
