Have you ever noticed the tiny patterns of lines in flower petals? These patterns actually act as guides for insects to move towards the glands that produce nectar which are at the base of the petals proving yet another brilliant creation of mother nature.
Kevlar, a reinforcing material used in bulletproof vests and tires, is the strongest manmade synthetic.
But can you believe that spider thread possesses properties that are far superior to Kevlar?
When fizzy drinks are produced, Carbon dioxide is dissolved in them under high pressure. As you drink these fizzy beverages,the carbon dioxide comes out of the solution and is collected as a gas in your stomach. When sufficient amounts of this gas have been collected, your body expels them through your mouth as burps.
If you are fond of soft drinks ,you have probably experienced burps after drinking soft drinks.Do you know the reason for this?
Have you ever experienced an unusual taste when drinking an orange juice after brushing teeth?This is caused by a compound called sodium lauryl sulfate(SLS).It temporarily, reduces the sensitivity of the taste buds which senses sweetness and enhances the sensitivity of the taste buds which senses bitterness.
If you were ever licked by a cat, you would have wondered why a cat’s tongue was so rough.The reason is the small backward thorn like structures on the surface of the tongue which have keratin in them.These make the tongue of a cat as rough as sand paper.
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.
When the gun powder packed in the fireworks burns, they give off hot exhaust gases that fire backwards.
According to Newton’s third law of motion,The surrounding air creates a reaction force that is equal and opposite in direction to the force of the exhaust gases that fire backwards which sends the fireworks shooting up in the air.
Rocket fireworks are one of the things that add beauty and colour to New year.Have you ever wondered how these fireworks rise to the sky?
Do you know who the natural inventor of paper manufacturing technology is? It’s none other than the wasp. To build their nests,wasps use paper that they make by mixing their saliva with shreds of chewed wood. Our furniture industry follows the same procedure to make chipboard,but using glue instead of saliva
Did you know that apart from being areas rich in bio diversity, wetlands/swamps also act as natural water purifiers?They improve water quality by filtering out pollutants like nitrogen ,phosphorous and sediments before they reach the river.
Breaking a cobweb definitely isn’t a hard task for you, but spider silk is much stronger and elastic than you might’ve ever imagined.The silk thread spun by spiders, measuring just 1 micro meter across, is five times stronger than steel of the same thickness.
There are 2 facts that affect the heat change of a bicycle pump when air is pumped by it.The friction between the piston and the cylinder releases heat when they are rubbed against .also, When the piston is pushed ,the air inside it gets compressed and the energy of the air molecules rises, resulting in a slight increase in its temperature
Why does a bicycle pump get heated when it is used to pump air into a tire?
A Wood frog can survive after its body gets mostly frozen and its heart stops beating during the arctic winter freeze. The glucose in its blood keeps its essential organs from freezing and enables them to melt in the spring and live on
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.
