Challenge: Make Your Own Paint

Say you run out of paint, but you’ve got a blank canvas or piece of paper that is just begging to be made into a painting. What do you do? Make paint from scratch! Humans have been making paint for millenia using whatever materials they’ve had on hand in or near their home. Now it’s your turn!

Your challenge is to make your own homemade paint, and use it to make art.

Your Homemade Paint Should:

• – Be wet enough to be used as paint
  You can use anything for to test your paint–a paintbrush, a q-tip, finger, sponge, cloth, toothbrush, or any other improvised “brush”
• – Be made from anything except actual paint!
  No need to buy anything, get creative with what you already have, ideas below 
• – Be used to make art!
  Show us that your paint works by making a painting

Materials Inspiration

There are many, many ways to make homemade paint. Part of this challenge is to figure out how to make paint out of materials, ingredients, and supplies you already have. Here are some places to start

Paint Material Ideas:

Stuff with good paint “texture” but not much color:

• • – No Recipe: Lotion, shampoo, sour cream, mud, craft glue, milk, toothpaste
  • – Goopy Recipe A: 1 tablespoon corn or potato starch + 1 cup water + microwave 30s + stir
  • – Watery Recipe B: 1/2 cup flour or cornstarch + 1/2 cup water + stir
  • – Chalky Recipe C: 1/2 cup crushed chalk/antacid tablets + 1/2 cup water + stir
  • – Gloppy Recipe D: 1/2 cup flour + 1/2 cup salt + 1/2 cup water
  • – Advanced Chemistry Recipe: Boiled red cabbage juice + liquids with different pH

Stuff that can be used for color pigment:

• • – Mashed or blended fruits and vegetables, especially beets, peppers, berries, spinach, red cabbage, carrots.
  • – Beverages! Gatorade, coffee, fruit juice, tea
  • – Artificially-colored foods: KoolAid™, Jello, food coloring, popsicles
  • – Plants! Grass clippings, flower petals, leaves, pollen
  • – Minerals! Dirt, rust, ash, clay, sand

Stuff that is basically already paint:

• • – Sauces: Ketchup, mustard, tomato paste, hot sauce
  • – Beverages: Coffee, tea, soda, cocoa, juice, smoothie, melted popsicles, sportsdrinks
  • – Wet earth: Clay, mud,

“Canvas” Material Ideas:

• – Paper
• – Cardboard
• – Wood
• – Fabric
• – Newsprint
• – Paper bags, plates, napkins
• – Sidewalk or driveway

“Brush” Material Ideas:

• – Paintbrush
• – Fingers!
• – Cut up sponge
• – Q-tips or cotton balls
• – Old toothbrush
• – Toothpicks, chopsticks
• – String, rubber bands
• – Balloon

Feeling Stuck? Try Some Ketchup

1. Find a sauce or condiment in your fridge, like ketchup, and squirt some onto a small dish
2. Get a piece of paper, newspaper, a paper plate, or a napkin for your “canvas”
3. Use a brush, or anything (like your pinkie finger) to make a smiley face on your canvas. Tadaa!

Now Challenge Yourself:

• – Try to make a whole set of paints that includes multiple colors.
  What colors are difficult to make? What colors are easy to make?
• – Try changing the consistency of your paint.
  How could you make it thicker, smoother, or thin it out so that it is runny like watercolors?
• – Get painting!
  How does your paint color change as it dries?
  What type of canvas would work best with the paint colors that you made?
  What changes could you make to improve your paint?
• – Do chemistry! Try making this paint that’s made with cabbage juice that changes color when you add basic or acidic liquids. It takes a bit more work, and some planning but can generate nearly every color of the rainbow!
