1 2 3 ACTION!!! HERE IS THE REACTION:

Many movies use scientific advancements to make their picture more realistic .The reverse has also happened.Movies frequently feature incredible new technologies, which are then read by people who are inspired to work on them. In fact chemical themes and characters have been capturing the imagination of audiences for decades. It is hard for people to notice the science of chemistry in movies and is so easily overlooked.

 

Everyone’s all time favourite Harry Potter series makes lot of references to the subject.

One by one, the Beauxbatons students stepped across the Age Line and dropped their slips of parchment into the blue-white flames. As each name entered the fire, it turned briefly red and emitted sparks.”

Both the commercial fireworks industry and traditional qualitative flame tests rely on colours produced when metal salts are heated to incandescence. Different salts are used to produce different colours. This is because the amount of energy needed to rearrange electrons into a higher orbit depends on the type of metal in the salt. Metals that absorb higher energies will release shorter wavelength light (e.g. blue) when their electrons return to a lower orbit and absorb lower energies emit longer wavelengths (e.g. red) .

 

During one Quidditch match in the rain, Harry couldn’t see clearly, his friend Hermione thinks of a perfect charm

I’ve got an idea, Harry! Give me your glasses, quick!” He handed them to her, and as the team watched in amazement, Hermione tapped them with her wand and said, “Impervius!” “There!” she said, handing them back to Harry. “They’ll repel water!”

Chemists have made available a wide variety of silicone-based, surface-active agents. Fabrics, paper, and glass can be given a thin coating of silicone polymer molecules, rendering the surface hydrophobic .

 

 

 

 

 

 

 

 

 

 

 

 

 

It is not only restricted to fantasy , in the popular novel “ The Strange case of Dr Jekyl and Mr Hyde”,Dr Jekyl is quoted saying

When a few drops of a strong acid/base is added to a dry-powdered compound, it will bubble and give off gases (Ebullition).Very few compounds change colour when they effervesce.’Unknown impurity’ quoted above was later identified to a compound of ergot called ergotamine.It was first synthesized in pure form by Arthur Stoll at Switzerland.

 

In the movie ,“Absent Minded Professor “,Professor Brainard ,invents a substance that gains energy when it strikes a hard surface. This discovery leads him to reverse a sign in the equation for enthalpyto energy plus pressure times volume. Brainard names his discovery Flubber, which is a portmanteauof "flying rubber."

It refers to a rubbery polymer formed by cross-linkingof polyvinyl alcohol(PVA) with a boroncompound. Being a non - newtonian fluid,it flows under low stress, but breaks under higher stresses and pressures.

 

Books like “The Time Machine”,” The War of the Worlds” and “The Invisible Man”, set the bar for science fiction. They are also among a number of books by Wells that had an impact on science itself. Science fiction offers hypothetical possibilities conceived by human-technological interactions.

 

Finally, we must realise that science in movies and books range from the actual, the plausible and the far-fetched .While some ideas from fiction may never become a reality, much of what we have read has in time ,come very close to the truth. Innovators relate to such ideas in an attempt to protect humanity and the only ‘earth ‘ we have.
