In a previous video, I described my accidental discovery of lead sponge, which you can see here https://youtu.be/1-NbDjxh_v0 A lot of you guys had questions and I decided to try and answer them. However, it ended up raising even more questions for me. So I embarked on a little journey of discovery to try and get to the bottom of it. I still have a bunch of questions though, and I hope you guys can help answer them. Nile talks about lab safety: https://youtu.be/ftACSEJ6DZA -------------------
