How did Dronacharya die??
In the battle of Kurukshetra, after the death of Bheeshma, Drona was the commander-in-chief of the Kauravas and is a quite fearless leader. His only weakness is his son Aswathama. So Krishna comes up with a plan to get rid of Drona. Bheem kills an elephant called Aswwatha and the next day in the battle, Yudishtar yells Aswathama Hatha Kunjaraha. He actually says the words 'Aswatha Hatha' in a loud voice and 'Kunjaraha' in a low volume that Drona couldn't hear. What that means is an elephant called Aswatha is murdered. Not knowing that Drona is distracted and that is when he gets killed.

How electric eels produce electricity?
The bodies of electric eels have electric organs that are made up of electrolytes. These organs are lined up and stacked allowing them the ability to store power, much like small batteries inside a torch. Hence, each cell adds to a potential difference and a current of ions can flow through them. Electric eels, with their electric ability can communicate, navigate and stun their preys. They can discharge upto 860 volts and one ampere of current.

Is JellyFish really a Fish?
Jellyfish aren’t really fish but gelatinous zooplankton; composed of 95% water. The remaining 5% is structural proteins, muscles and nerve cells. They are made of a jelly-like material 'Mesoglea'. They got no brain, heart, bones or blood. They came 500 million years back, primitive to even dinosaurs. Some are even bioluminescent, producing their own light. Heard of Box jellyfish? The most venomous marine animals in the world! A type of jellyfish, Turritopsis Dohrnii is the only animal in the world that can reverse its lifecycle and hence called immortal.

What causes Lightning?
Colliding particles of water vapour and ice inside clouds create electrical charges. Heavier negative charged particles sink to the bottom of the cloud and positively charged particles accumulate at the top. When these electrical fields become large enough, a giant spark of electric discharge is created. This causes lightning. Most lightning occurs between clouds but a few occur between clouds and the earth. A flash of lightning contains up to 1 billion volts of electricity and can heat the surrounding air to temperatures 5 times hotter than the sun’s surface.

Why does the sky appear blue?
Sunlight is made of different colours of light which have different wavelengths. The atmosphere of the earth is composed of very small molecules of Nitrogen, Oxygen, Water Vapour, Carbon Dioxide, Argon and traces of other gases. These molecules scatter the shorter and higher-energy wavelengths of light more efficiently than other wavelengths. Though violet light is scattered more than blue light, our eyes respond more strongly to blue light and hence the sky appears blue.
