In this article, we will delve into the world of squishy see-through eggs, exploring their composition, the materials needed for their creation, and a step-by-step guide on how to make them.
Introduction to Squishy See-Through Eggs
Squishy see-through eggs are essentially a form of polymer experiment that results in a soft, clear, and somewhat fragile egg-shaped object. The primary material used in making these eggs is a specific type of polymer that, when mixed with water, undergoes a process called cross-linking. This process transforms the liquid mixture into a solid, yet pliable, substance. The transparency and squishiness of the eggs are what make them so appealing, as they can be handled gently without breaking and provide a clear view of any object placed inside them.
Understanding Polymers
Before diving into the process of making squishy see-through eggs, it’s essential to have a basic understanding of polymers. Polymers are large molecules, or macromolecules, composed of many repeating subunits called monomers. When these monomers are linked together through chemical bonds, they form polymers. The properties of a polymer, such as its strength, flexibility, and transparency, depend on the type of monomers used and the way they are linked. In the case of squishy see-through eggs, the polymers used are typically derived from polyvinyl alcohol (PVA) or Sodium Polyacrylate, which are known for their ability to absorb and retain water, making them ideal for creating soft and clear objects.
Polyvinyl Alcohol (PVA) vs. Sodium Polyacrylate
Both PVA and Sodium Polyacrylate are commonly used in making squishy see-through eggs, but they have different properties and uses. PVA is more commonly used for its clarity and the ability to dissolve in water, making it easier to manipulate and shape. On the other hand, Sodium Polyacrylate is known for its superabsorbent properties, making it capable of absorbing hundreds of times its weight in water. This property makes Sodium Polyacrylate-based eggs more squishy and resilient to deformation.
The Making of Squishy See-Through Eggs
Making squishy see-through eggs involves a few simple steps and some basic materials. The process can be a fun and educational project for both children and adults, offering insights into chemistry and material science.
Materials Needed
To start making squishy see-through eggs, you will need the following materials:

– Water
– A container for mixing
– A mold in the shape of an egg
– Optional: food coloring, glycerin
Step-by-Step Instructions
Prepare the Mold: Before mixing the polymer, ensure your egg mold is clean and dry. If you’re using a plastic egg mold, you might need to lightly grease it with cooking spray to ensure the egg will come out easily once it’s set.
Mix the Polymer Solution: In your mixing container, combine the polymer powder with water. The ratio of polymer to water can vary depending on the desired consistency and clarity of the egg. Generally, a higher concentration of polymer will result in a clearer but less squishy egg, while a lower concentration will make it more squishy but potentially less clear. Start with a small amount of water and add more as needed, stirring continuously to avoid lumps.
Add Color (Optional): If you want to add some color to your egg, now is the time to do it. A few drops of food coloring can turn your egg into a vibrant, see-through orb. Mix well to ensure the color is evenly distributed.
Pour into the Mold: Carefully pour the polymer solution into the egg mold. Make sure to fill the mold to the top to get the full shape of the egg.
Allow it to Set: The setting time can vary greatly depending on the type of polymer used and the ambient temperature. It can take anywhere from a few hours to overnight for the egg to fully set. Once set, the egg should be firm to the touch but still slightly yielding.
Remove from Mold: Gently remove the egg from the mold. If it sticks, you can run the mold under warm water for a few seconds to loosen it.
Tips and Variations
- Glycerin Addition: Adding a small amount of glycerin to the polymer solution before pouring it into the mold can help retain moisture in the egg, making it softer and more resistant to drying out over time.
- Experiment with Shapes: While egg shapes are traditional, you can experiment with different molds to create various shapes of squishy, see-through objects.
- Combining Materials: For a more complex project, you can combine PVA and Sodium Polyacrylate to achieve a balance between clarity and squishiness.

By using the right materials, you can create a squishy see-through egg that is both fun and realistic.
How do I mix the egg white and yolk mixture?
To mix the egg white and yolk mixture, start by combining 1 cup of water with 1 tablespoon of glycerin in a bowl. Stir the mixture well until the glycerin is fully dissolved. Then, add a few drops of food coloring to the mixture and stir again to distribute the color evenly. For the yolk, mix 1 tablespoon of glycerin with 1 tablespoon of water and a few drops of food coloring in a separate bowl. The yolk mixture should be thicker and more vibrant in color than the egg white mixture.
Once the mixtures are ready, slowly pour the egg white mixture into the plastic container or egg mold, followed by a small amount of the yolk mixture in the center. Use a stirrer or spoon to create a marbled effect by gently swirling the two mixtures together. Be careful not to overmix, as this can cause the egg to become too solid or uneven in texture. Allow the mixture to sit for a few minutes before adding the borax solution to help it solidify. With the right mixture and technique, you can create a realistic and squishy see-through egg that is perfect for crafts or decorations.
What is the role of borax in creating squishy see-through eggs?
Borax plays a crucial role in creating squishy see-through eggs by acting as a catalyst to help the mixture solidify. When the borax solution is added to the egg white and yolk mixture, it reacts with the glycerin to form a cross-linking network that gives the egg its squishy texture. The borax solution should be made by dissolving 1 tablespoon of borax in 1 cup of water, and then stirring until the borax is fully dissolved. The solution should be added slowly to the egg mixture, stirring constantly to ensure that it is evenly distributed.
