Freaky Friday was released in 1976/77. Do you know what this means?? That was a movie Stanford Pines saw and it inspired him to build the Electron Carpet!!
Ford Pines was not a man who was very interested in heading out into the town for some casual, regular fun. He was too busy entwined in untangling the mysteries of Gravity Falls, or working on his other scientific inventions/pursuits at the time.
But one day in 1977, he was exploring the town for any sign of anomalous activity, when he saw something strange dart into a nearby building. He tried to chase after it, but was held up when the teenager at the door asked for his ticket. Confused, he backed up and realized he was standing in front of the only cinema in town.
Glad he’d for once brought his wallet on a trip to town (he knew he needed some more groceries, and once he was done with the routine check, he’d wanted to grab them so he wouldn’t be forced to make a second trip to town and let the rumor mill about him catch fire again) he bought a ticket for the first movie he saw, and hurried inside.
He searched all over for the thing he’d been chasing, but it seemed to have disappeared for the time being. But then! He caught it in his peripheral vision and he ran towards it, following it into a dark theater.
Taking a seat in the back, he followed the creature’s progress with his eyes. It stopped a few rows ahead of him and sat down in the chair on the end of the row, looking ready to flee at the slightest of provocation. Ford decided to keep to his back seat hideout and observe from there. He made many mental notes as he watched it, barely aware of what was going on with the movie in the background.
But that didn’t mean he didn’t pick up subconsciously what was going on in the movie The ideas sparked by the movie flowed around in his brain days after the incident in town. (Which turned out to be none other than Toby Determined, which he’d mistaken for an actual anomaly).
About a week after seeing the movie, he began writing down notes on the feasibility and building design of something to switch the essence of a person into another without losing any essential parts. From that he created Experiment 78: The Electron Carpet. He initially managed to capture small animals to test if it worked between them first, then he moved on to the gnomes and animals.
But he trusted no one in town to switch bodies with, and he could not even imagine asking a couple of them to come to his cabin to test its capabilities. So for a couple more years, it went untested by humans. Until Fiddleford came up, that is.
Ford told him about the carpet ahead of time, so Fiddleford was prepared for the effects, but it was still one of the stranger experiences Fiddleford had had (but overall benign, it did not upset him the way the portal activities did). Fiddleford told Ford it reminded him of that groovy movie that had come out a few years ago. Ford said that was ridiculous, and he’d appreciate it if Fidleford did not compare his work to such gaudy works of fiction in the future.
Little did Stanford realize how exactly on the nose Fiddleford’s comparison was.
