A gummy bear placed in water will exhibit a significant increase in size, specifically growing 2 centimeters in length and expanding 1 centimeter in width from its original dimensions, while also becoming notably more jellylike in texture.
Understanding Gummy Bear Growth in Water
Gummy bears are primarily made of gelatin, sugar, and water. When submerged in water, they undergo a fascinating process driven by osmosis. Gelatin is a hydrogel, meaning it can absorb large amounts of water. The higher concentration of sugar and other solutes inside the gummy bear compared to plain water creates a concentration gradient. Water molecules from the outside move into the gummy bear to balance this gradient, causing it to swell.
The Science Behind the Swell
This phenomenon, known as osmosis, is a fundamental biological process where water moves across a semi-permeable membrane from an area of higher water concentration (lower solute concentration) to an area of lower water concentration (higher solute concentration). In the case of a gummy bear:
- The gummy bear acts like a semi-permeable membrane.
- Water molecules rush in to dilute the concentrated sugar solution within the bear.
- This influx of water causes the gummy bear to expand in all dimensions.
Key Growth Dimensions and Texture Changes
Based on experimental findings after being removed from the water, a gummy bear demonstrates specific changes in its dimensions and texture:
- Length Expansion: The gummy bear shows a remarkable increase in its overall length.
- It grows 2 centimeters in length from its original size.
- Width Expansion: Beyond length, the gummy bear also expands significantly across its width.
- Its width expands 1 centimeter compared to previous measurements.
- Texture Transformation: The absorption of water drastically alters the gummy bear's consistency.
- The texture becomes far more jellylike, losing its initial firm, chewy quality.
Summary of Gummy Bear Growth
The following table summarizes the observed growth metrics:
| Dimension | Growth/Change |
|---|---|
| Length | +2 Centimeters |
| Width | +1 Centimeter |
| Texture | Becomes more jellylike |

Practical Insights
Observing a gummy bear grow in water is a classic science experiment that effectively illustrates the principles of osmosis. The degree of growth can sometimes vary slightly based on factors such as:
- The initial size and brand of the gummy bear.
- The temperature of the water.
- The duration of submersion.
This simple experiment provides a tangible example of how water movement can impact physical properties and dimensions.
