1. Lightest Solid Aerographene or graphene aerogel is considered to be the lightest solid material on Earth, with a density of 160g/m 3 or in other words, it is approximately 7.5 times less dense than air (however if we consider the air incorporated in the structure as well, then its heavier than air). It is so light that it can balance on a flower without deforming it (as shown in the above image). 2. Strongest Acid     The strongest acid is fluoroantimonic acid. It is a mixture of hydrogen fluoride and antimony pentoxide. It is so corrosive that it can eat through glass.   3. Most Toxic Substance   The main difference between toxin and poison is that toxin is obtained from a living organism while poison may be obtained from living organisms or may be made artificially. The most toxic substance till date is the botulinum toxin (botox) produced by the bacterium Clostridium botulinum (which causes botulism). It is so toxic that only 0.00007 mg of botox is enough to kill a 70kg man

Fun Facts about Animals

1. THE IMMORTAL JELLYFISH Can an organism actually be ‘immortal’? Only one animal is known to have such a remarkable ability and that is a jellyfish named Turritopsis dohrnii , also known as the ‘immortal jellyfish’.   It was first discovered in the 1880s in the Mediterranean Sea. The Turritopsis dohrnii can switch between life stages. Whenever, it faces any kind of environmental stress (like starvation), it changes itself to a blob of tissue, pretty much like a frog changing to a tadpole. Now of course, it isn’t completely ‘immortal’ and can be killed by other means. 2. TRIBOCUS CAMELUS   What is the maximum number of humps a camel can have? Generally, camels have a single hump (in case of Dromedary camels) or two humps (in case of Bactrian camels). But, a three humped camel colony was found in Oman in the Rub al-Khali desert. This new species has been given the name ‘ tribocus camelus’.  3. THE LIVING DEAD How does a starfish survive without any brain and blood?
