I don't know in which language to continue this discussion, but I'll use English, then everyone will understand wat I'm saying . Tyneman, you said that compositions without NH4Cl won't work very well. In the video posted by pudidotdk, table salt (NaCl) is used, and that also works pretty well (nice video ). So are there two or more types of chlorides you can use for this composition, or am I wrong about the table salt?
