dave321 Posted March 2, 2015 Share Posted March 2, 2015 just found out the composition materials for the Z16, Z16A, Z17, and Z17A Spark Hitsby de lamarenot surprisingly - Zirconium / Potassium perchlorate compositionAppearance - Bead of dark grey powderdeposited onto a plastic resin base andsealed in a clear lacquer membrane. Thebead encloses a resistance wire in contactwith insulated connecting wiresnot surprisingly you don't need much for a great spark effect that outperforms Titanium or Aluminium sparks hands down, for a theatrical bullet hits metal spark effect (obviously not a realistic effect, but a visually impressive film effect) Link to comment Share on other sites More sharing options...
