The very definition of the word is deeply entrenched in the world of science, but there's another meaning commonly associated with the word 'chemistry'. If most school children could have linked chemistry to pro wrestling, perhaps the subject would have taken on more interest, but it's actually vital to how the industry works. As pertains to in-ring grappling, chemistry dictates the 'emotional or psychological interaction between two people'. It also comes in to play when analysing the physical interaction between those who step foot inside a wrestling ring together. Chemistry can be vital in ensuring matches are exciting or successfully manage to draw fans into the action. There are numerous examples of those pairings who exhibited excellent chemistry, such as Steve Austin and The Rock or Kurt Angle and Chris Benoit. Any time those men were handed the opportunity to work opposite one another, there was magic in the air. On the other side of the equation, what about those combinations who - for whatever reason - simply didn't click or gel when working one another? Going even further, there have been those pairings that really should have produced better matches than they did. Individually, both guys were awesome, but just couldn't get on the same page during their bouts.
