How Orbeez are made?

Orbeez are made from a superabsorbent polymer called sodium polyacrylate. This polymer has the unique ability to absorb and retain large amounts of water relative to its size.

The manufacturing process involves mixing the polymer with water and colorants to create the small, hard beads. These beads are then dehydrated, resulting in a dry product that can be stored and shipped easily.

When Orbeez come into contact with water, the polymer chains expand, allowing water molecules to enter and be retained within the beads.

The beads can swell to a size several times larger than their original form, creating the soft and pliable texture that makes them so appealing for sensory play.

Note that while Orbeez are safe and non-toxic when used as intended, they should not be ingested, and parental supervision is recommended, especially for young children.

Why do Orbeez shrink?

Orbeez, those colorful and squishy water beads, have gained popularity as a sensory toy and a decorative item.

Why do Orbeez shrink?

They start off as small, hard beads but when placed in water, they absorb it and expand, transforming into soft and bouncy orbs. However, you may have noticed that over time, Orbeez can lose their original size and shrink.

Below, we are discussing the scientific explanation behind why Orbeez shrink and discuss the various factors that can contribute to this phenomenon. We will compare different factors and their effects on the shrinking of Orbeez.

Scientific explanation of why Orbeez shrink

Orbeez are made of superabsorbent polymers, which have the ability to absorb and retain large amounts of water.

When these polymers come into contact with water, they undergo a process called osmosis. Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration through a semipermeable membrane.

Initially, the dry Orbeez beads have a lower water concentration compared to the surrounding water.

As a result, water molecules pass through the semipermeable membrane of the beads and are absorbed by the polymer chains within. This absorption causes the beads to swell and increase in size.

However, as time goes by, the concentration of water inside the swollen Orbeez beads becomes higher than that of the surrounding water.

Consequently, the water molecules start to move out of the beads through osmosis, seeking to equalize the concentration on both sides of the semipermeable membrane. This outward movement of water causes the Orbeez to gradually lose water and shrink in size.

Factors that can cause Orbeez to shrink

  1. Time: The longer Orbeez are left in water, the more time they have to undergo the osmosis process and release water, resulting in shrinkage.
  2. Temperature: Higher temperatures can accelerate the osmosis process, causing Orbeez to shrink faster. Conversely, lower temperatures can slow down the process, prolonging the size retention of the beads.
  3. Exposure to air: When Orbeez are exposed to air, the evaporation of water molecules from the beads occurs more rapidly. This can lead to quicker shrinkage compared to when the beads are submerged in water.
  4. Humidity: In high-humidity environments, the moisture content in the air is increased. This can affect the rate of evaporation from the Orbeez, potentially leading to faster shrinkage.

Comparison of different factors and their effect on Orbeez

When comparing the different factors mentioned above, it becomes evident that time is the primary factor contributing to the shrinkage of Orbeez.

The longer the beads are immersed in water, the more water they will absorb initially, and subsequently release over time, resulting in greater shrinkage.

Temperature and exposure to air are secondary factors that can influence the rate of shrinkage. Higher temperatures and increased exposure to air tend to expedite the osmosis process and evaporation, respectively, leading to faster shrinkage.

Humidity, although it can affect evaporation, plays a relatively minor role compared to the other factors mentioned.

Understanding the factors that contribute to the shrinkage of Orbeez allows us to better manage their size retention and prolong their squishy playtime.

Please note that these factors are generalized and may vary depending on the specific brand or type of Orbeez used.

It’s always a good idea to refer to the manufacturer’s instructions for the best practices regarding Orbeez play and maintenance.

Can Orbeez be restored?

Orbeez, the popular water-absorbing beads, have captivated people of all ages with their vibrant colors and squishy texture.

Can Orbeez be restored?

However, over time, you may notice that Orbeez can shrink, losing their original size and plumpness. This raises the question

Techniques for Restoring Shrunken Orbeez

  1. Water Rehydration Method: One of the simplest ways to restore shrunken Orbeez is by immersing them in water. Fill a container with room-temperature water and place the dried-out Orbeez in it. Allow them to soak for several hours or overnight. As the Orbeez absorb the water, they will gradually regain their original size and plumpness. Remember to use clean water and avoid adding any substances that may damage the Orbeez.
  2. Ice Water Method: For a quicker restoration process, you can try the ice water method. Fill a bowl with a mixture of ice and water, ensuring the water remains cold. Place the shrunken Orbeez in the bowl and let them sit for about 15 to 30 minutes. The cold temperature will help the Orbeez absorb water more rapidly, causing them to expand. Once they have reached the desired size, remove them from the ice water and let them dry before use.
  3. Hot Water Method: Alternatively, some people have had success with the hot water method. Boil a pot of water and remove it from heat. Carefully place the shrunken Orbeez into the hot water and allow them to soak for a few minutes. The heat will cause the Orbeez to expand and regain their original size. After the desired restoration is achieved, drain the hot water and let the Orbeez cool down and dry before use.

Common Mistakes When Attempting to Restore Orbeez

  1. Overhydration: While adding water is essential for restoring shrunken Orbeez, it’s important not to overhydrate them. Over time, Orbeez can reach a saturation point where they won’t absorb more water. Exceeding this limit may cause them to burst or lose their texture. Follow the recommended soaking times and avoid leaving Orbeez submerged in water for prolonged periods.
  2. Using Chemicals: It’s crucial to avoid using chemicals or substances other than water when attempting to restore Orbeez. Some chemicals may alter the composition of the beads or cause them to deteriorate. Stick to using clean water without any additives to ensure the best results and the longevity of your Orbeez.
  3. Rushing the Process: Patience is key when restoring Orbeez. While it may be tempting to speed up the rehydration process, rushing it can lead to unsatisfactory results. Allow the Orbeez ample time to absorb water naturally and avoid forcing them to expand using excessive measures, as this may damage their texture and quality.

Tips for Maintaining the Size and Quality of Orbeez

  1. Proper Storage: To prevent Orbeez from drying out and shrinking, store them in an airtight container or resealable bag when not in use. This will help maintain their moisture content and ensure they stay plump and ready for play.
  2. Avoid Direct Sunlight: Orbeez should be kept away from direct sunlight, as exposure to UV rays can cause them to fade and deteriorate over time.


In conclusion, Orbeez have captured the imaginations of both children and adults alike, with their mesmerizing colors and tactile appeal.

We’ve discovered that these tiny water beads can indeed shrink over time when exposed to air or left to dry. However, note that you can revive them by rehydrating with water.

As you explore the fascinating world of Orbeez, keep in mind these key takeaways: First, proper storage in a sealed container can help maintain their size and shape for longer periods.

Second, the rate of shrinkage can vary depending on environmental factors, so it’s essential to consider humidity and temperature.
