The idea of the bubble test goes back at least to the 1930s and is used by many as a way to grade student understanding of basic principles. If you’re like most people, you probably think of a bubble test as something that involves blowing bubbles through a straw into a cup of soapy water. But did you know that there’s actually a scientific way to test the strength of bubbles?
The bubble test is used to determine the amount of air in a given sample of soap solution. By measuring the force required to burst the bubbles, scientists can calculate the surface tension of the soap solution. To know more about bubble leak tests, you can also check out this site.

Surface tension is caused by the attraction of water molecules to each other. This attraction creates a sort of “skin” on the surface of the water that minimizes contact with other surfaces (like air).
Bubbles form when this skin is broken, usually by some sort of agitation (like blowing into a straw). The size of the bubble is determined by how much surface area is available for the skin to stretch across.
The stronger the surface tension, the larger the bubble will be. The Bubble Test is a test that is used to determine the purity of a substance. It is also known as the Air Release Test. The test is simple; a sample of the substance being tested is placed in a container of water and then air is bubbled through the water. If the substance being tested is pure, then the bubbles will be small and uniform. If the substance being tested is impure, then the bubbles will be large and irregular.
