Have you ever heard of creatures that use fiber optics? A certain species of sponge living in the Antarctic seas has the ability to collect the light it requires with their spicule like structures of optical fibers and is a source of light to its surroundings .This technology is used to transmit solar rays to parts of skyscrapers that receive no direct light.Lenses sited in a skyscrapers roof focus the sun’s rays on the ends of fiber optic transmitters which then send light to even the darkest places of the building.

Honey is hygroscopic, meaning that it will absorb water from things, even from the air. This has the effect of providing almost no free water for microbes to grow.It is too acidic for most microbes. Honey also contains an enzyme which can break down its glucose into hydrogen peroxide under the right conditions.That’s why honey is not easily spoilt like other food.

A king fisher enters the water to grab its prey without creating a splash with the help of the streamlined shape of its beak.This concept is used to reduce the noise created when bullet trains travel through tunnels. These trains are designed with a streamlined forefront, which not only solved the noise problem but also increased the speed and efficiency of the train.
