Some years ago, while strolling along the picturesque Seine River in Paris, I came across a mesmerizing sight: giant bubbles floating gracefully on the riverbank. It was a beautiful summer afternoon, and the bubbles seemed almost magical. Crowds had gathered around two street performers who were skillfully creating these enchanting bubbles using nothing more than a pair of sticks and a special soapy water mixture.

As a passionate scientist with a keen interest in bubbles, I knew that the real secret to making these giant bubbles lay in the precise combination of the soapy water mixture. The sticks, though helpful, were not the true source of their magnificence. This realization made me appreciate that bubbles were more than just playthings for children; they held within them a world of fascinating science.

Let’s delve into the captivating science behind creating bubbles and even eliminating the tiniest ones. Soap bubbles, those shimmering spheres that captivate us with their ever-changing colors, are crafted from simple ingredients we encounter every day: air, water, and soap. The magic lies in the interaction between light and the varying thickness of the bubble’s surface, causing the colors to dance and shift.

Water, a compound made up of hydrogen and oxygen molecules, possesses a property known as surface tension. This surface tension gives water droplets a tendency to curve inwards, forming a semihemisphere shape. When soap is added to water, it reduces the surface tension, making the water more elastic and conducive to bubble formation. Think of bubbles as mathematical problem-solvers, continuously striving for geometric perfection. The shape with the least surface area for a given volume is a sphere, which is why a single bubble always takes on this shape.

Interestingly, when bubbles come into contact with each other, they cleverly share a common wall, minimizing the use of materials. As more bubbles join the ensemble, their arrangement shifts, giving rise to intriguing geometries. Six bubbles, when brought together, form a remarkable cube at their center, showcasing the power of surface tension in creating the most efficient structure.

Now, let’s explore bubbles from a different perspective. During one of my daughter Zoe’s visits to the Marwell Zoo in Southern England, she noticed that penguins swimming beneath the water left trails of bubbles in their wake. Curious, she asked me why they did so. As it turns out, penguins have evolved a remarkable ability to utilize bubbles to reduce the density of water around them.

Emperor penguins, known for their impressive diving skills, store air under their feathers before submerging. As they swim, they release the trapped air as a cloud of bubbles, effectively decreasing the density of the water. This clever adaptation allows them to swim faster, boosting their speed by up to 40 percent. Inspired by these remarkable creatures, ship manufacturers have developed an “air lubricating system” for large ships, which reduces water resistance and saves up to 15 percent of energy during transportation.

Beyond their natural wonders, bubbles have found applications in medicine as well. Microbubbles loaded with drugs and magnetic agents can be injected into the bloodstream, guided by magnets to specific areas in the body. Once they reach their target, ultrasound waves can be used to burst the microbubbles, delivering the medication precisely where it’s needed. This noninvasive delivery system shows promise in transforming medicine.

However, as a scientist working on ink formulation, I understand the challenges that bubbles can pose. Even in the ink production process, tiny bubbles can become trapped, introducing unwanted oxygen and moisture. In applications such as organic light-emitting diodes (OLEDs), these trapped bubbles can lead to the appearance of dark spots in pixels over time. Removing microbubbles from the ink requires innovative techniques, such as passing the ink through a thin, porous tube within a vacuum chamber, effectively squeezing out the bubbles and ensuring a high-quality product.

In conclusion, my fascination with bubbles extends beyond their enchanting beauty. Bubbles are intricate entities that hold within them a wealth of scientific principles and applications. From the delicate balance of surface tension to the ingenious adaptations of penguins and the potential of bubbles in medicine, these seemingly simple spheres captivate our imagination and invite us to explore the wonders of the world around us.
