Ingredients

  • 1/4 cup cornstarch
  • boiling water
  • cold water
  • 3 or 4 teaspoons colored liquid tempera paint

Instructions

  1. Mix cornstarch with cold water to make a smooth, thick paste.
  2. Stir in boiling water until you reach the desired consistency; the mixture should become thick, lose its white appearance, and turn fairly clear immediately.
  3. Spoon the mixture into paint cups or jars.
  4. Add liquid tempera paint and stir to combine.

Tips & Substitutions

To achieve the best texture, ensure the cornstarch is fully dissolved in cold water before adding boiling water. If you prefer a more vibrant color, add more liquid tempera paint gradually until you reach your desired hue. You can also experiment with different colors and combinations to create unique shades. If you need a thicker paint, reduce the amount of boiling water slightly.

Serving Suggestions

This cornstarch-based paint is perfect for arts and crafts activities with children. Set up a painting station with brushes, sponges, and various materials to paint on, such as paper or fabric. It pairs beautifully with fun projects like Zucchini Cups for a creative afternoon, allowing kids to express themselves artistically while enjoying healthy snacks.

Storage & Reheating

Store any leftover paint in airtight containers to prevent it from drying out. It can last for about a week in the refrigerator. If the paint thickens over time, you can add a splash of cold water and stir until you reach the desired consistency again before use.

Frequently Asked Questions

Can I use food coloring instead of tempera paint?
