Ok, this surprised me. I'm doing a science project on superconductivity, so I was browsing the web for chemistry and physics stuff and I saw some experiments that looked interesting (solidifying liquid nitrogen) on youtube. I wondered where they got the chemicals because I thought it would be illegal, but I googled it and saw a place. What shocked me is that people are selling Uranium ore. Isn't that illegal? Did anyone else here know about this? I found out that it's a joke on amazon, but one place is selling it. I'm not sure if I should post the name here.
