If you’d like to take a crack at anodizing your titanium camping gear, try submerging it in Coca-Cola and running 20v-100v ~~through~~ across it. This can be achieved using 9v batteries and a little patience. Depending on the voltage applied, you can transition between Bronze, Blue, Light blue, Yellowish, Purple, Cyan, and Green.

Interesting technique, but I must correct an error. One does not “run” voltage “through” anything. Voltage – across, current – through.

  Yes, that spork does look familiar! And it’s a thing of beauty, isn’t it.

ummm… plain ole salt water works. You just need ions to make the water conductive.

The concept of daisy chained 9 volt batteries is clever and doable by everyone.

Can this be done with other metals, like Aluminum?
