Homemade bath fizzies are a functional craft that teaches children about chemical reactions while producing high-quality gifts. By using food-grade ingredients and simple kitchen tools, kids can create spa-quality items for friends and family without the additives found in commercial brands.

Safety and Handling for Citric Acid

Standard Round Bath Bombs

ages 5+ · 30 min · about $1.50 each

  1. Whisk baking soda, citric acid, Epsom salt, and cornstarch in the bowl until no lumps remain.
  2. Combine the coconut oil and essential oil in a small glass, then slowly pour into the dry mixture.
  3. Use gloved hands to rub the oil into the powder until it is evenly distributed.
  4. Mist the mixture with water one spray at a time, mixing immediately to prevent fizzing.
  5. Test the texture; it should feel like damp sand and hold its shape when squeezed in your fist.
  6. Pack the mixture tightly into both halves of a sphere mold and press them together firmly.
  7. Allow to dry in the mold for 24 hours before removing.

Cookie Cutter Bath Melts

ages 3+ · 20 min · about $1 each

  1. Place a sheet of parchment paper on a flat baking sheet.
  2. Set the metal cookie cutters onto the parchment paper.
  3. Scoop the damp bath fizzy mixture into the center of each cutter.
  4. Press the mixture down with your thumb or the back of a spoon until it is level and packed tight.
  5. Carefully lift the cookie cutter straight up to leave the shape on the parchment.
  6. Let the shapes air dry for at least 48 hours until they are hard to the touch.

Toy-Filled Surprise Fizzies

ages 6+ · 40 min · about $2.50 each

  1. Fill one half of the silicone mold halfway with the bath fizzy mixture.
  2. Press the mixture down to create a small indentation in the center.
  3. Place the plastic toy into the indentation, ensuring it does not touch the sides of the mold.
  4. Cover the toy with more mixture until the mold half is overflowing.
  5. Fill the second mold half with mixture and press both sides together firmly.
  6. Brush away any excess powder from the seams and let sit for 24 hours.

Gift-Ready Packaging

ages 4+ · 15 min · about $0.50 per bag

  1. Cut the cardstock into 4-inch wide by 3-inch tall rectangles to serve as bag toppers.
  2. Fold the cardstock rectangles in half horizontally.
  3. Place one dry bath fizzy into a cellophane bag.
  4. Fold the top inch of the bag over to seal it.
  5. Slide the folded cardstock topper over the folded edge of the bag.
