Looking into getting a few of these cold spark machines for my events but some sites say they require permits and other say they do not. Don't really care about "being certified" as Ive handled a lot more explosive shhhh...
...buuut, you know how these event producers and facility managers are, oh wait, and the FIRE DEPT MARSHALS. Just want to get the low down on em.
Anyone currently using them, have any feedback on them.
