Instructions
Preparation
- In a mixing bowl, add 1 cup of cornstarch and break up any clumps for a smooth mixture.
- Pour in 1/2 cup of water and stir slowly until combined. Notice how it feels thick at first!
- If desired, add a few drops of food coloring and stir to mix evenly.
- Gently stir in your pH indicator solution and observe the color change based on the pH.
