    Avoided because I thought it was about drugs and didn't care Realized it might be about tumbleweed in actuality and stayed. You might have got the druggie clicks but at what cost?

    This went from trying to deal with tumbleweeds to splicing genetic traits from tumbleweeds into plants used for food production. Please if someone remembers send me a reminder so I can watch when the lead scientist has the camera zoomed in close yelling "IT"S ALIVE!, IT"S ALIVE!!!".

    I actually worked in that lab, a long time ago when I was an undergrad at CSU! Summer of 2002, and I just did the normal undergrad menial bs. The only thing of interest that I can remember was there was a big steam cooker at the back of the greenhouse. Whenever we got done removing weeds (whether their experimental usage was complete or if we had removed them as part of a separate pest control study) we’d have to place them in the steam cooker to completely destroy them. If we just tossed them in the trash or in the compost, they’d continue to spread seed and “infect” other areas of campus. The smell of the plant matter after steaming it in the pressure cooker was beyond words; it was easily the smelliest part of my day. And since we were pressure cooking them with steam, it was also the most dangerous!
