Possible source of SS electrodes?

[flapdoodle]

I noticed Walmart has some fancy travel mugs that are double walled stainless steel and claim to be insulated. Looking inside told me the inner container is cylindrical. Can't tell if the outside if the outside of the mug is SS or not, but it is sculptured rather than cylindrical.

The item is marked on the bottom as a Walmart product made in China. Cost is about $7

It may be possible to disassemble it and use the outer part as the HHO generator jar as well as one electrode, remove the insulation and use the inner cylinder as the other electrode.
