How to Make Polymer Putty [Gak|Flubber|Slime]

Things You Will Need

  • Bottle of Elmer's Glue (4 oz.)
  • Borax (1/2 teaspoon) I can give you some Borax.
  • Warm water
  • Gallon zip lock freezer bag
  • Small cup
  • Measuring cup (1/4 cup)
  • Measuring spoon (1/2 teaspoon)
  • Food coloring (optional)

Instructions

Make a 50% Glue Solution

1. Pour 4 ounce bottle of Elmer's Glue into a gallon-size zip-lock bag.
2. Re-fill glue bottle with warm water. Cover the opening and shake it up before pouring the water into the mixing bowl.
3. Add some food coloring to glue solution. You can seal the bag and squish it around to uniformly mix the color into the glue solution.

Make a 4% Borax Solution

4. Pour 1/4 cup warm water into a cup.
5. Add 1/2 teaspoon of borax to the water and stir to dissolve. It may not all dissolve.

Combine to Form Polymer Putty Mixture

6. Pour a small amount of the Borax solution into the glue solution and mix it. You will notice an immediate change as the glue stuff becomes stringy. Repeat adding and mixing until all the Borax solution is in the glue solution. 
7. With the bag sealed, keep squishing the mixture until it becomes a slimy flubbery polymer putty.
8. Store your polymer putty in the bag to keep it from drying out.

Warnings

  • This is a messy activity.
  • Keep the putty away from hair, cloth, paper and carpet. It is still a glue and will adhere to porous things. It could ruin your carpet if it dries there. However, the putty is easily cleaned from skin and non-porous surfaces with regular hand-soap and water.
  • Borax is soap. I use 20 Mule Team Borax (I have lots of it left over since it is sold in a big box.) Don't ingest the borax. Like any other laundry detergent, it could make you sick if eaten or cause a rash if applied to your skin. (There doesn't seem to be enough borax in the putty to cause any adverse reaction with skin when you are handling it. And I encourage you to handle the putty.)

Things to Do with Polymer Putty

  • Play with it on a surface like plastic or Formica that is impermeable to liquids. Your putty is a liquid with some of the qualities of a solid.
  • Make a putty ball and bounce it. 
  • Hold up a ball of putty and let it ooze out between your fingers. Make long oozy trails of flubber. Squish them together and do it again. Stretch it. Snap it. Squish it. Splat it.
  • Put the putty into a plastic cup, trapping some air, and squish it to make rude noises. I don't recommend glass because glass can crack under pressure and severely cut you.
  • Stack it up and watch it "melt" into a smooth pool.
  • Stick a drink straw under it and blow bubbles. See who can make the largest bubble. Pop the bubbles.
  • Play with the putty while it is in the bag. I like to blow air into the bag before I seal it, then shake the putty around to form funny shapes that look like brains or worms and stuff.
  • Use the lesson to teach science by learning about solutions, mixtures, polymers. Research Elmer's glue, borax, etc.
  • Use the lesson to teach art. Use the putty to glue papers together as it dries. Make a cool craft.  Make putty of different primary colors and mix them to make new colors. Yellow + red = orange. Red + blue = purple. Yellow + blue = green. Yellow + red + blue = brown.
  • Use the lesson to teach math by learning percentages and measurements. Is this really a 4% solution?

Spiritual Lesson: I will live for God.

1 Timothy 5:22. "Do not share in other people’s sins; keep yourself pure."

Sinning does not please God. Sinning is like spiritual filth. Some people fall into sin by copying other people or seeing something sinful on television. That is a shameful.

1 Corinthians 15:33. 'Do not be deceived: “Evil company corrupts good habits.” Awake to righteousness, and do not sin; for some do not have the knowledge of God. I speak this to your shame.'

Sinful ideas and evil habits are like glue without the soap. Bad habits want to stick to you and make your life messy. However, God wants you to be clean and stay clean. 

1 Thessalonians 5:22. "Check out everything, and keep only what’s good. Throw out anything tainted with evil."

You cannot shake off a sinful habit. It would be more difficult than shaking glue off your hands. You need God to change you first. When you add the soap to the glue, it transforms! The glue can be removed after it turns into putty. You can literally throw it off!

Romans 12:2. "And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God."

God can both clean you up and  keep you clean. Soap is good for cleaning dirty clothes or scrubbing a filthy floor. What kind of soap do you use to clean up? But soap cannot clean your heart. Only God can do that. Soap cannot free you from sinful habits. Only God can do that. 

3 John 9. "Beloved, do not imitate what is evil, but what is good."

With God's help, you can say, "I will keep my heart clean." Pray for God to forgive you, transform you and empower you to live a victorious Christian life!
