the week: an experiment

Cheryl mentioned that there was a way to keep rocks looking shiny.  (Bake them in mineral oil at 200F for 3 hours.)  So we tried it.

It turned out pretty well, but we didn't remember what they looked like before.

Then we tried a bigger rock.

It is more obvious in this picture!  Oddly enough, the mineral oil wicked up a little bit.  I wasn't expecting that.

The mineral oil leaves a bit of a residue, so Isaac washed it in water.  It still looks good!
