Yeah, the color change is due to cystals of oxides of copper, iron and zinc (Bronze), It is a thin film interference. I made this instructable since their was no one like it on Instructable.

I want to do this with copper pipes know it will work since it copper but I can find Thiourea dioxide which 500 g cost 40 dollars CAN and Thiourea alone is 70-80 dollars alone for 30 g.Would thiourea dioxide work instead?Thiourea dioxide + water >>>>> Thiourea + Hydrogen peroxide.Tin (II) chloride plus H202 should give Tin (IV) chloride and tin hydrooxychloride.6 SnCl2 (aq) + O2 (g) + 2 H2O (l) → 2 SnCl4 (aq) + 4 Sn(OH)Cl (s).However in excess Hydrochloric acid oxygen from the Hydrogen peroxide and some chlorine gas will be emitted. 2HCl + H202 >>> 2H20 + Cl2.I am not entirely sure but would chlorine negatively effect the plating due to its reactivity?Most likely tin chloride (IV) would reverse back to tin (II) chloride and have little effect.

It an interesting concept. BTW it would NOT be recommended probably for Bipolar or people very sensitive to sleep. It because lack of sleep can trigger Mania and other symptoms like Psychosis in Bipolar. I could see this if done properly treat mild to moderate depression and it may reduce symptoms of severe depression but that ALWAYS requires antidepressant as a treatment too.I know a friend with Bi and if he overexposed to blue screen at the TV, videogames or computer it makes his Mania worse.It not for everbody tho.

Although my incubator isn't as complex it uses a thermometer one outside and one inside. I am using it to grow broths of bacillus L bacteria that produce a NATURAL selective insecticide. A 20W CFL does not release enough IR heat to raise the temp to 25-35 degrees C. Ideal for these bacteria.

Do you know what the acetic acid does to the glycerin and the starch? I assume it helps produce glucose polymers that may link to each other. Is it possible to use dyes that glow under UV or would they be effected by acetic acid. I know a solution of sodium fluorescien work best at pH 6-7 so having an acetic environment may prevent it from glowing under UV. Dyes like Indigo carmine, Malachite green, Safranin O, India Ink could they be used with this green plastic?
