so colourful

nice rite? this is what happen when u mix different ratio of nikel and ethylene diamine(en). the colour change is so consistent. Take a look at the blue spectrum, the variation is so consistent until it turns purple. cool rite??!! When mixing, u can actually see the colour change within the solution. awesomeness. wonderful. miraculous.
