You can also make a pinhole camera. Click here to see how to make the device that lets light pass through a hole and project an image of the sun onto a light surface.
Can I look at the sun at any time during the eclipse?
You can look at the sun during the eclipse while wearing certified eclipse glasses, welding glass (level 14) or other filters. You can look at the sun without the protection ONLY during the two minutes or so when the moon completely blocks out the sun. Only look at the sun without glasses if you live in the area of totality – a narrow strip of the country where the sun will be completely blocked out.
For the rest in the area where the sun is only partially blocked out, keep the glasses on. Do not look at the partially blocked sun without them.
So what if I do look at the sun without protection?
You could, and likely will, damage your retina, leading to vision damage.
What if I want to see it, but not go out to look at it?
No problem, all the major networks, and cable channels will be carrying the eclipse live. ABC, NBC, CBS, PBS, CNN, Fox and other cable outlets have plans to broadcast the progress of the eclipse across the country.
NASA will livestream the eclipse starting at 1 p.m. ET. NASA plans views from balloons, satellites, and telescopes.
What about taking a photo? Will it damage my iPhone?
The eclipse won't damage your phone's camera, according to c/net. C/net's post explains how to use your iPhone or an Android phone to capture the eclipse.
