Let’s experiment with polymers…

GAK Recipe


Pour glue and coloring in plastic container.

Stir until color is thoroughly mixed in.

Add starch a little at a time, stirring with a spoon or kneading with your fingers as mixture thickens.

Keep stirring until mixture holds together like putty.

Test with your fingers: if too sticky, add more starch in small amounts until mass is smooth and rubbery.

Silly Putty Recipe

This will bounce and pick up pictures from the paper just like the name-brand stuff.

  • Add: 1/2 cup water to 1/2 cup Elmer’s glue (Not School Glue!)
  • Mix and add 3 drops of food coloring (optional)
  • Make Borax solution: Take 2 tablespoons borax (You can buy this at a grocery store oronline) and add to 1 cup of water and stir.
  • Add 1/2 cup of Borax solution to water and glue mixture
  • Stir and store in a plastic bag

Mix well. Add food coloring if you wish. Let it dry about an hour. When ready, it will be smooth and rubber-like. Store in an airtight container.

Flubber Recipe

  • Put 3 T. of water into a ziploc bag.
  • Add 1 T. of white glue.
  • Add 2 heaping T. of Borax (laundry detergent). It must be Borax.*

Shape into a ball. If the mixture is too sticky, roll the ball in a little bit of Borax. Enjoy stretching this elastic substance.

Oobleck Recipe

2 cups of corn starch

3 drops of green food coloring

enough water to make a thick mixture (about the texture of pancake batter)  I usually measure equal amounts of water and corn starch, but mix water in slowly.

Mix all ingredients together. This makes a fun mixture to play with textures. Use different utensils, such as a spatula, bowl, and funnels, to see what form the mixture will take.

Play-Doh Recipes…

Cornstarch Dough

  • 1/2 cup salt
  • 1/2 cup hot water
  • 1/2 cup cold water
  • 1/2 cup cornstarch

Mix salt and hot water and boil in pot. Stir cold water and cornstarch in a separate bowl. Add cornstarch mixture to boiling water and stir. Cook over low heat, stirring until “pie dough consistency”. Remove from heat and place dough on board. When cool, knead dough until smooth. Have fun playing!


texture is grainy

hardens in 1-2 days

dough will be white

to speed dry, put in 200 degree oven for 1 hour

will keep for a long time if stored in a container


Scented Play-Doh: (smells awesome and the kids LOVE IT!)

  • 1 package of sugar free gelatin; .3 oz size (use any flavor you want, as the dough will have that scent when done; I believe you can replace the gelatin with a Kool-Aid packet instead for even more scented varieties!)
  • 2 cups flour
  • 1 cup salt
  • 4 tablespoons cream of tartar
  • 2 cups boiling water
  • 2 tablespoons cooking oil

Mix dry ingredients together in pot, add the boiling water and cooking oil. Stir over medium heat until it forms a ball. Let it cool. Keep in air tight container in refrigerator when not playing with it.


Chocolate Scented Play-Doh:

1 1/4 cups flour

1/2 cup cocoa powder

1/2 cup salt

1/2 tablespoon cream of tartar

1/2 tablespoon cooking oil

1 cup boiling water.

Mix flour, cocoa powder, salt, and cream of tartar together. Add cooking oil and boiling water to mixture. Stir quickly and mix well. Cook over low heat until dough forms a ball. When cool, mix with your hands. Store in airtight container.

Note: It smells good enough to eat, but tastes awful! Is NOT EDIBLE.
