    The answer to the extra credit question is…light bulbs in asparagus cans! Tell us about a time you’ve had to DIY something sciencey.

      i made a telescop inn my childhood using glasses lens, paper for tube and some other lens from some broken camera or so for the ocular - we did not have much choice back in ussr so it was not just for fun but also for nessesity

      How was anyone supposed to know that if you didn't tell us? I didn't realize this was the answer to the question from this week's video and tried to figure it out myself. I've got the internet and couldn't figure out the answer.

    Nice slides! It's been literal decades since I learned any of the basics, but never once did we get to see images like THAT. Only drawings in the science textbooks - which, I'm not knocking those, science illustrators have one of THE coolest jobs and sometimes a very challenging one. But those pretty and simplified pictures just don't convey the organization and complexity the same way. That said, I do still recall even 30-plus years later, the demonstration of "how xylem works" using food coloring and a stalk of celery. The slides are cooler though!

    Eventhough I've known that leaves have a vascular system, but it's still so weird to me how closely it parallels the animal vascular system with blood. Makes cutting a leaf seam abit more violent.

    I love this host - honestly I'm a big Tasha the Amazon fan (shout out to Floralogic) and I would LOVE to see those two do a plant trek video or something. I feel like their vibes are both just *chefs kiss* Ugh why are plant people always the coolest people

    How did I make it over 30 years of my life without learning that plants can be affected by viruses? I thought they only had to worry about funguses

    When I was in elementary school I bought a microscope that used a mirror to reflect light through my slides. I still have it.

    As a vegan, the fact that plants seem alive makes me uncomfortable that I’m eating them.

    I heard photosynthesis started as 2 cells becoming one, like mitochondria. Is this true?
