Ingredients
  

Baking Soda Galaxy Ornament Dough
  • 1 cup baking soda base of the ornament dough
  • 0.5 cup white vinegar reacts with baking soda to form dough
  • 0.5 cup cornstarch adds silky feel and helps ornaments keep shape
  • 0.25 cup corn syrup keeps dough pliable and easy to work with
  • food coloring in galaxy shades (blue, purple, pink, silver, black) to create marbled effect

Equipment

  • Large bowl
  • Parchment Paper
  • Cookie Cutters
  • Straw or Skewer

Method
 

  1. Step 1: Cover your work surface with parchment paper or a cloth to keep things tidy.
  2. Step 2: In a large bowl, mix the baking soda and cornstarch thoroughly.
  3. Step 3: In another bowl, gently mix the white vinegar and corn syrup; fizzing is normal.
  4. Step 4: Slowly pour the wet mixture into the dry ingredients while stirring until you get a soft, pliable dough that doesn’t stick.
  5. Step 5: Divide the dough into portions and add a few drops of galaxy food coloring to each; fold gently to create a marbled galaxy effect.
  6. Step 6: Shape the ornaments with cookie cutters or by hand. Poke a hole near the top for hanging before drying.
  7. Step 7: Let the ornaments air dry flat on parchment paper for about 24 hours until completely hard.

Notes

Use honey or golden syrup as a substitute for corn syrup if desired. Add edible glitter or metallic food gels for extra sparkle. Scent with vanilla or cinnamon extract if you'd like a festive aroma. After drying, paint white stars or constellations with acrylic paint for extra flair.
