Hello, I want to know how can I make crystals. I have read your post and I want to know that why you used a copper mug? Can't we use any mug or copper mug is important? I am also searching for a site online in which I can read legit service review because I am thinking about hiring an essay writer online to complete all my assignments. I want to make a crystal because I am doing a science project and for that I need a crystal. I am making a planet in which scientists will found crystals and will bring them to earth to make a laser that will kill cancer cells from your body.
