I love this dope science music video on gems and minerals, which features some of our talented young people in the Teen Advocates for Science Communications (TASC) program at the California Academy of Sciences. Warning: it's quite an earworm.
By the way, if you have not seen the new Gems and Minerals Unearthed exhibit at the California Academy of Sciences, it's pretty great!
UPDATE 4/11/17: A couple of rocks and minerals were incorrectly labeled. So a new version of the video has been uploaded. Remember, science is about the continual improvement of knowledge, not getting it right the first time!
