in 1729 stephen gray was experimenting with static electricity, which he generated using a glass tube. he noticed that a cork, used to protect the tube from dust and moisture, also became electrified (charged). further experiments (e.g, extending the cork by putting thin sticks into it) showed – for the first time – that electrical effluvia (as gray called it) could be transmitted (conducted) over a distance. gray managed to transmit charge with twine (765 feet) and wire (865 feet). through these experiments, gray discovered the importance of different materials, which facilitated or hindered the conduction of electrical effluvia. john theophilus desaguliers, who repeated many of gray’s experiments, is credited with coining the terms conductors and insulators to refer to the effects of different materials in these experiments. gray also discovered electrical induction (i.e., where charge could be transmitted from one object to another without any direct physical contact). for example, he showed that by bringing a charged glass tube close to, but not touching, a lump of lead that was sustained by a thread, it was possible to make the lead become electrified (e.g., to attract and repel brass filings). he attempted to explain this phenomenon with the idea of electrical effluvia.

andrew kreisberg, creator and executive producer on both series, said, "it's really going to be an adventure with the arrow and flash on both episodes. watching the two teams come together and fight alongside each other, it's one of the most fun parts, ... we just don’t believe in waiting. we really believe in accelerated storytelling." kreisberg explained that since they are all comic book fans themselves, they have all debated the age-old question of which superhero would win in a fight; "so, the idea that [the flash and arrow] would fight each other in one of these episodes was one of our earliest ideas, and that the cast members would have that comic-con argument on camera was one of our earliest ideas." greg berlanti, creator and executive producer on both series, explained that "crossovers are part of [the characters'] dna, ... and if we waited ..., then we would be depriving the audience of something we all wanted to see".
