• 2). Immerse one to two white coffee filters into the solution for about three minutes.
  
  
• 3). Remove the now yellow coffee filters and let them dry out on a cookie sheet overnight. Speed up the drying time by placing the cookie sheet with filters in your oven. Set the temperature at 150 to 200 degrees.

Test for pH

• 1). Mix 1/2 tsp. baking soda into the glass of water, dissolving it.
  
  
• 2). Dip one of your dried pH swab indicators into the baking soda/water solution. Notice the color. If the color remains yellow, you have an acidic substance. If the color turns red, you have a base or alkaline substance.
  
  
• 3). Test other substances such as black coffee, saliva, water, vinegar, tomato juice, lemon juice, soapy water, eggs and your shampoo.
