  • Some plants are known to collect heavy metals etc.

  • @trzcinarowice I mention such issues in the related article on my website.

  • @EatTheWeeds, I have a bucket of rainwater collected from my house roof, I accidentally dropped a new penny into it and retrieved it with a neodymium magnet. Along with the penny, I found the magnet also picked up lichen washed from the roof. Can you shed anylight on why this is? I can't find any info on the internet.

    Thanks,

    Locouk.

  • @locouk Lichen grow on nearly anything that's been around for a while. It also could have fallen on the roof from a tree. Got a picture? 

  • I have come across a lot of trees out in the country full of old mans beard lichen and since you have the thing about DDT and such I am worried to collect them. How far away from a farm would you say would be safe to collect?

  • @FloweringFamily Dust can travel. DDT also degrades with time. GIve yourself a mile or so.

  • I Love You and your vids!!!! : )

  • @EatTheWeeds I've no photo atm, it looks like a black gunk of small decomposed particles. Upon lifting the magnet from the water some fall away in a cloud which rapidly sink. There are no overhanging trees, but I guess it' is a lichin. I'll post a video when I get some time and get a close up of the stuff.

  • When I saw the lichen there and you mentioned how old it could be it made me think of it as a terrestrial form of coral. "Land coral." :-)
