Is the science accurate?
Can the chemicals they release into the tornadoes really cause them to weaken in real life?
shareNo. It's bullshit. Throwing baby diaper absorbent materials into a tornado isn't gonna change them or make them lose moisture. All it's gonna do is make the tornado throw it all over the place and add to the debris. You would need something enormous to suck all the moisture away from the storm, something far larger than packages of baby diaper material. A tech that doesn't exist, basically.
The closest real-life equivalent to that silly idea, that I've seen on tv, was an orchard farmer in a Southern State that had special air-cannons he used to disrupt the air over his farm to prevent hailstorms. I'm not sure if it worked, but he seemed to think so. He claims that he's had less hailstorms hit since he started using them.
He would fire them off when he'd hear about the air-pressure changing prior to a thunderstorm heading in the direction of his farm. They were pretty loud, so everyone in the vicinity had to get a prior warning and put on hearing protection. The whole idea was, he'd use them to change the air-pressure in the immediate area to disrupt the worst storms so they wouldn't be as strong when they arrived, or they would dissipate entirely.
