Injecting vegetables one at a time to speed things up a week!?!? He stabs all the way through the stem also, you can see the liquid spilling onto the ground, looked like his first time doing that.
I think the dying green and spraying probably happens unfortunately and people can detect it so they’d be more likely to believe there is a drug that can make vegetables double in size overnight (and apparently cause no obvious other ill effects) and the same sort of people who scammed them are using it. Seems like a part true scare story to get views or whatever.
