So far this is a GREAT lighted magnifying glass. I love the size and the clarity of the lens as well as the placement of the light source. I also like the fact that the light does not go on automatically every time I pop out the lens for use. I have the choice to turn on the light or to leave it off. That will help to extend the battery life.

I've had my Mighty Bright magnifier light for over a year. I knew my brother-in-law would love it for Father's Day since he is a crossword puzzle enthusiast! Great product, many uses, perfect, unique gift!

The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. The molecules at the surface of a glass of water do not have other water molecules on all sides of them and consequently they cohere more strongly to those directly associated with them (in this case, next to and below them, but not above). It is not really true that a "skin" forms on the water surface; the stronger cohesion between the water molecules as opposed to the attraction of the water molecules to the air makes it more difficult to move an object through the surface than to move it when it is completely submersed.

Within a body of a liquid, a molecule will not experience a net force because the forces by the neighboring molecules all cancel out (diagram). However for a molecule on the surface of the liquid, there will be a net inward force since there will be no attractive force acting from above. This inward net force causes the molecules on the surface to contract and to resist being stretched or broken. Thus the surface is under tension, which is probably where the name "surface tension" came from. (Source: Woodrow Wilson Foundation).

The cohesive forces between molecules in a liquid are shared with all neighboring molecules. Those on the surface have no neighboring molecules above and, thus, exhibit stronger attractive forces upon their nearest neighbors on and below the surface. Surface tension could be defined as the property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of the water molecules.

It seems to defy the laws of physics, but a paper clip made of steel can indeed float on the water surface. The high surface tension helps the paper clip - with much higher density - float on the water.

I've had these for several years. One button on the side came off and it was difficult to use so, I ordered more. The light and inset magnifier make a huge difference

Due to the surface tension, small objects will "float" on the surface of a fluid, as long as the object cannot break through and separate the top layer of water molecules. When an object is on the surface of the fluid, the surface under tension will behave like an elastic membrane.

Basler ace GigE Cameras have a small form factor matching an analog cameras, making them an economical replacement, and are available at Edmund Optics.

Surface tension in water might be good at performing tricks, such as being able to float a paper clip on its surface, but surface tension performs many more duties that are vitally important to the environment and people. Find out all about surface tension and water here.

Water molecules want to cling to each other. At the surface, however, there are fewer water molecules to cling to since there is air above (thus, no water molecules). This results in a stronger bond between those molecules that actually do come in contact with one another, and a layer of strongly bonded water (see diagram). This surface layer (held together by surface tension) creates a considerable barrier between the atmosphere and the water. In fact, other than mercury, water has the greatest surface tension of any liquid. (Source: Lakes of Missouri)

I have used these magnifier glasses for years, each one last me about a year before they wear out, I constantly use them every day and evening. After looking for the last 12 years of using these, they are the only ones I found that consistently works in last for a long period of time. they easily fit in my shirt pocket.
