Oklahoma Agriculture in the Classroom



Veggie Ink

Each student needs:

  • 9-ounce clear plastic cup
  • 1 teaspoon unsweetened powdered drink mix (e.g., Koolaid)
  • 1 teaspoon water
  • 1/8 teaspoon soybean oil (vegetable oil)
  • 1/8 teaspoon granular soy lecithin (found in health food stores)
  • stir stick
  • paper towel
  • rubber stamp images, paint brush, sponge or other painting implement


  1. Using a stir stick, blend water with the packet of drink mix in the clear plastic cup.
  2. Add soybean oil and stir well.
  3. Add granular soy lecithin and continue stirring until the lumps are gone.
  4. Fold a paper towel in half and then in half again. This is the stamp pad.
  5. Carefully pour the contents of the cup into the center of the folded paper towel.
  6. Print images on sheets of paper to create stationary, cards, wrapping paper, etc.

Note: The ink will take a little extra time to dry and can stain fabric.

Students should note that soy oil does not mix well with water until lecithin is added. Soy lecithin is a byproduct of soap-making, used for mixing fats and oils with water. Lecithin is a common ingredient in fatty foods such as chocolate bar and salad dressing.
