Simple Eclipse Tool

prusaprinters

Whipped up this quick eclipse observation tool for observing the sharp/fuzzy shadow phenomenon and for pinhole projection. I got the idea to observe these from youtuber Destin Sandlin of the channel SmarterEveryDay. He has a fantastic video explaining these things in detail. Check it out! Hopefully this tool can help folks observe some awesome eclipse phenomena! You'll need to supply a white sheet or posterboard, and use this tool to cast some crazy eclipse shadows!
