|April 18, 1969
Summary
Researchers created exceptionally long-lasting and large soap bubbles using improved solutions. These enhanced bubble formulations incorporated water-soluble synthetic organic polymers, significantly extending bubble lifespan and size.
Area of Science:
- Surface science
- Polymer chemistry
Background:
- Traditional soap bubble solutions have limited lifespan and size.
- Understanding factors affecting bubble stability is crucial for various applications.
Purpose of the Study:
- To develop soap bubble solutions capable of producing bubbles with extended longevity and increased dimensions.
- To investigate the effect of specific synthetic organic polymers on bubble stability.
Main Methods:
- Formulating bubble solutions with water-soluble synthetic organic polymers, including polyvinyl alcohol and polyoxyethylene.
- Producing and measuring the lifespan and diameter of soap bubbles generated from these enhanced solutions.
- Defining bubble life as the time to contract from original size to a flat film.
Main Results:
- Successfully produced soap bubbles with lifespans exceeding 2 years.
- Generated large-volume bubbles, reaching over 100 liters and 60 centimeters in diameter.
- Demonstrated that addition of polymers like polyvinyl alcohol and polyoxyethylene significantly enhances bubble durability.
Conclusions:
- Water-soluble synthetic organic polymers are effective in dramatically increasing soap bubble lifespan and size.
- The developed bubble solutions offer potential for new applications requiring stable, large-scale bubbles.

01:22Cell Size
Cell sizes vary widely among and within organisms. Bacterial cells range between 1-10 micrometers (μm)and are considerably smaller than most eukaryotic cells. The smallest bacteria are 0.1 μm in diameter—about a thousand times smaller than eukaryotic cells, which typically range from 10-100 μm.Surface AreaCells can take in nutrients and water via diffusion through the plasma membrane itself or through specific channels in the membrane. The area of the membrane surrounding the cells limits the...
01:17Gross Anatomy of the Liver
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is covered...

01:17Gallbladder
The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins the common...

01:21External Anatomy of the Kidney
The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

01:23Urinary Bladder
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

01:13Problem Solving: Volume
The volume of a fuel tank mounted on the wing of a jet aircraft can be modeled using the concept of solids of revolution. In this case, the tank is formed by rotating a two-dimensional region, defined by a mathematical function, about the x-axis. The region extends along the axis from zero to two meters, and the resulting three-dimensional shape is symmetric about the axis of rotation. Because the boundary curve lies directly against the axis, the disk method is an appropriate technique for...
