So once you have collected all of those you need to set it up in the obvious way. Heat Proof Mat, Bunsen Burner on top of that, Tripod hovering over top, Gauze Mat on top of the Tripod and then Bunsen Burner.

Put zinc-nitrogen in-to the Busen Burner and put in on orange flame until its boiling the change the flame to blue put the 10c coin in for 10 mins and then get it out and put it under water then put it under the blue flame for 5 mins and wet it the wipe it with a paper towel
