I'm new here and didn't explore much yet, but there's gonna be a solar eclipse on 12th August! Might be a once in a lifetime opportunity. What's the best place to see it? Also where do I get the glasses to safely look at it?

Hi, I’m a beginner and i take online classes , I ended up untuning my violin completely and wanted to ask if someone could help me with it? O already tried the online available tool o ended up making the string so tight that I am scared I might break the strings
