With youngsters blaring Spotify on their headphones loud enough for the whole bus to hear, it is only natural for elders to advice you to keep your iPods turned down. Forget that for a minute and listen to this.
Little do we know that a simple and innocent kiss can do a far worse damage to your ears. It is something that sounds like fiction, more like an urban legend and seems like a story I understand, is tough to believe.In case you do not believe me, I have included references at the end of the article. It is weird, but I believe it is important for people to be informed about it.
Kissing on the ear, a kiss that involves suction, has the ability to create a negative pressure on your ear drum and can cause serious injury to it. It can cause intense pain due to the pulling of ossicular chain and due to the ear drum getting dislodged. The symptoms may vary anything from a constant ringing sound, hearing loss to certain kind of sounds, distortion or even complete hearing loss.

What is Watermelon Snow?
Watermelon Snow, exactly as the name suggests, is a pink colored watermelon slushy like snow. It has been spotted in a number of snow covered regions of the earth which are permanently covered with snow. Although the pink color may look like it comes from some sort of a mineral deposit, or some other inorganic source such as meteorite debris, interestingly it is due to living organisms – Algae. Its other names are – snow algae, pink snow, red snow, or blood snow.
How does it get that color?
One of the widely found algae species in these pink snow patches contains a red pigment (called carotenoids) in addition to the green chlorophyll component. The alage itself is called Chlamydomonas nivalis.

If you had a formal education that touched even a little bit of composite materials in the course, you will immediately be able to recall what these amazing materials can do. For others, Composite materials, as the name suggests, are materials that are composed of two or more different kinds of materials.
In a simple case think of your body, which is, in a broad sense, a combination of skin material and bone material. These materials are designed to take advantage of the contrasting properties of, say two different materials. For simplicity’s sake, skin is soft and bone is hard. The bone gives body a solid structure, while the skin and muscle tissues enables this hard skeleton to make fluid movements – flex or bend – and still be together.
Individually the materials that make up a composite material are not very capable. But when they come together, composite materials can blow your mind. To appreciate how this simple coming together of two humble materials can create a super material, and to appreciate the mind blowing properties it can have, let us first look at what most of us have heard of – “Carbon Fiber”. We will get into the more mind bending aspect of composites after that.
Carbon Fiber Reinforced Polymers (CFRP)
Now carbon fiber itself isn’t a composite material. As the name suggests, it is a fiber of carbon. The fiber is composed of strands of carbon each of which are much thinner than a single human hair. Hundreds of these come together to form a thicker fiber. This fiber can be woven to make sheets or the carbon fiber itself can directly be used in a composite material.
