SUCCESS !!!

I have achieved controlled nucleation !   Using a finer etch produced ZERO results, but changing liquids to beer over sparkling apple juice allowed nucleation to happen over my previously etched area !   You can see a smiley face in the beer foam........ the smiley i had etched to begin with.  Granted it looks a bit like a Picasso, but its visible :)   Next up on nucleation process will be to media etch with a courser media and see what happens............ SCIENCE AND BEER !!  I am being both entertained and educated........ i hear that is the best way to learn.  The beer is a local brew, Mother's Brewing Company, Winter Grind.  It produces a fantastic head, but for this, i slow poured into a slanted glass, and then allowed it to settle after taking a few sips :)
