Measuring and Mixing the Components
The first step in making eraser putty is to measure and mix the correct components. You will need the following ingredients:
- 1/2 cup white school glue
- 1/4 cup water
- 1 tablespoon borax powder
Once you have gathered your ingredients, you can begin the mixing process. Follow these steps carefully:
Mixing the Glue and Water
First, pour the white school glue into a mixing bowl. Then, gradually add the water to the glue while stirring constantly. Stir until the glue and water are well combined and there are no lumps.
Adding the Borax Powder
Once the glue and water are mixed, it’s time to add the borax powder. Be sure to add the borax powder slowly while stirring constantly. This will help to prevent the mixture from clumping up. Continue stirring until the borax powder is completely dissolved and the mixture is smooth and elastic.
As you stir the mixture, you may notice that it begins to thicken and become more like putty. This is a good sign, as it means that the reaction between the glue, water, and borax is starting to take place.
Once the mixture has reached the desired consistency, you can stop stirring and pour it into a mold or shape it into a ball with your hands.
Kneading and Shaping the Putty
1. Kneading the Putty
Start by taking a small piece of the Borax solution and adding it to the glue mixture. Mix well until the putty starts to form. Add more Borax solution as needed until the putty becomes smooth and elastic.
2. Shaping the Putty
Once the putty is formed, you can start shaping it into any desired shape. Roll it into a ball, flatten it into a disk, or mold it into a specific object. Be creative and experiment with different shapes and textures.
3. Finishing Touches
After shaping the putty, it’s important to give it a final touch to enhance its functionality. Here are some tips:
| Tip | Description |
|---|---|
| Smoothing the Surface | Rub the surface of the putty with your fingers or a wet cloth to smooth out any rough edges or imperfections. |
| Adding Color | If desired, you can add color to the putty by mixing in food coloring or acrylic paint. Work the color thoroughly into the putty until it’s evenly distributed. |
| Drying the Putty | Let the putty air-dry for several hours or overnight. This will allow the putty to fully cure and become more durable. |
Achieving the Ideal Consistency
The ideal consistency for eraser putty is soft and pliable, but not so soft that it becomes sticky. It should be able to mold easily into various shapes and textures, yet firm enough to pick up and erase pencil marks effectively.
To achieve the ideal consistency, follow these steps:
- Start with the correct ratio of ingredients. The basic eraser putty recipe calls for 2 parts white school glue to 1 part borax powder.
- Mix the ingredients gradually. Add the borax powder to the glue a little at a time, while stirring constantly. This will help prevent clumping.
- Stir until the mixture becomes thick. Continue stirring until the mixture becomes thick and gooey. It should have a consistency similar to thick honey.
- Knead the mixture. Once the mixture is thick enough, remove it from the bowl and knead it with your hands. This will help to distribute the borax evenly throughout the putty and make it more pliable.
- Adjust the consistency as needed. If the putty is too soft, add a little more borax powder. If it’s too firm, add a little more glue. Continue kneading until the putty reaches the desired consistency.
The ideal consistency of eraser putty will depend on the brand of glue and borax used, as well as the temperature and humidity of the environment. It may take some experimentation to find the perfect ratio and kneading time for your specific materials.
Here is a table that summarizes the steps for achieving the ideal consistency:
| Step | Description |
|---|---|
| 1 | Start with the correct ratio of ingredients. |
| 2 | Mix the ingredients gradually. |
| 3 | Stir until the mixture becomes thick. |
| 4 | Knead the mixture until it reaches the desired consistency. |
| 5 | Adjust the consistency as needed. |

Scientific Principles Behind Eraser Putty
Eraser putty, also known as silly putty, is a viscoelastic material that exhibits both solid and liquid-like properties. Its unique behaviour can be attributed to the following scientific principles:
1. Viscoelasticity
Eraser putty is a viscoelastic material, which means it has both viscous and elastic properties. When a force is applied to it, it flows slowly like a liquid, but it also springs back to its original shape like a solid. This combination of properties gives eraser putty its characteristic “bouncy” feel.
2. Polymer Network
Eraser putty is composed of a network of long, chain-like molecules called polymers. These polymers are entangled with each other, creating a strong but flexible structure. When a force is applied to eraser putty, the polymer chains slide past each other, allowing it to flow. However, when the force is removed, the polymer chains return to their original positions, restoring the putty to its original shape.
3. Van der Waals Forces
The polymer chains in eraser putty are held together by weak intermolecular forces called van der Waals forces. These forces are responsible for the putty’s cohesiveness and its ability to adhere to surfaces.
4. Surface Tension
Eraser putty has a high surface tension, which means it tends to form a smooth, rounded surface. This property helps eraser putty conform to the shape of the objects it comes into contact with.
5. Chemical Composition
Eraser putty is typically made from a combination of silicone oil, boric acid, and other ingredients. The exact composition of eraser putty can vary depending on the desired properties. For example, adding more silicone oil can make the putty softer and more pliable.
6. Temperature Dependence
The properties of eraser putty are temperature-dependent. It is softer and more pliable at higher temperatures and harder and more elastic at lower temperatures. This is because the polymer chains become more flexible at higher temperatures, allowing them to flow more easily.
7. Non-Toxic
Eraser putty is non-toxic and safe for use by children. However, it should not be ingested.
8. Uses
Eraser putty has a wide variety of uses, including:
- Erasing pencil marks
- Cleaning hard-to-reach areas
- Stress relief
- Art projects
9. Variants
There are many different variants of eraser putty, each with its own unique properties. Some of the most common variants include:
| Variant | Properties |
|---|---|
| Magnetic putty | Contains iron particles that make it magnetic |
| Glow-in-the-dark putty | Contains phosphorescent pigments that make it glow in the dark |
| Scented putty | Contains fragrances that give it a pleasant smell |
