The Great American Eclipse is happening!
If you plan to view the sun directly, make sure you have special filters (eclipse glasses) that meet the ISO 12312-2:2015 standard. Even with those, don't spend a lot of time looking at the sun.
The safest way to watch the eclipse is with your back to the sun. Make a projector and watch the images. If you project the image onto paper, you can trace projections of the eclipse over time so you have a permanent record of your day.

Here's some Eclipse Science (from last Wednesday)
I'll be watching the eclipse using my favorite pinhole projector: a hole poked through a paper plate. (Though I might use the cereal box, too)
Have fun and be safe! Remember to put on sunscreen and don't look at the sun without your special eclipse filters.
