Project Aragonite: Day 15.
Well, we have a little more activity with the growth of aragonite. Finally, some crystals have grown on the rock itself, plus much more along the walls of the glass jar. I’ve barely been on Tumblr, which is why I wasn’t able to update this project until now. The vinegar has evaporated enough to expose the top half of the rock, so more crystals should continue to grow! I have the rock in direct sunlight to help the process of growing the crystals more successful as well. As the vinegar continues to evaporate, more and more crystals will grow. Here’s an awesome example of someone’s popcorn rock after all the vinegar evaporated on YouTube.
