How to view the solar eclipse

How to see the solar eclipse
On August 21, 2017, between 9 am PST and 3 pm EST (check your timing here) everyone in North America will be able to see a partial solar eclipse! People in 14 states will be in the path of totality and will have the chance to see a total solar eclipse and observe the Sun’s corona! (If you couldn’t already tell, we are pretty excited!!)
[For more information on eclipses, you can take a look at our picture guide.]
The 2017 solar eclipse is approaching – but what if you don’t have eclipse glasses? No worries, you can appreciate this solar phenomenon using some simple projection devices you can make at home.
Projection devices work by focusing the sun’s light onto another surface so that you can safely view the sun indirectly. During a partial solar eclipse, projections of the sun’s rays will appear in a crescent shape that changes with the position of the moon! Pinhole projectors are very cool, very old devices that date back thousands of years.
SAFETY NOTE: You should never look directly at the sun without the special type of solar filter found in eclipse glasses. DO NOT use regular sunglasses.
1. The Simple Pinhole Projector
This is probably the easiest and most well-known form of projection. All you need is a piece of card stock (or cardboard) and a pin. Poke a hole in the center of your card stock to make your pinhole projector. Position your projector over a light piece of paper or light sidewalk until you see the small circular projection of the sun appear on the paper. That’s it!
Pro tip—cut a hole in the cardboard and cover it with aluminum foil before poking your holes. The foil makes it easier to get a crisp projection, and you can easily poke multiple holes to project a fancy pattern.
2. The Pinhole Hat
You can create a pinhole viewer that goes over your head. We like to call this a pinhole hat. To create one, you need a large box, some white paper, duct tape, and some aluminum foil.
Get a very large box. Tape one side closed with dark masking or duct tape. This is the top of your “hat”.
Identify the two sides of the box that are the farthest apart, and label one side “front” and the other side “back”
Fold closed the bottom of the box. Create a hole for your head in the bottom the box towards the back (have an adult do this part). It helps to place the hole as close as you can to a corner.
On the side labeled “back” cut a square hole in the corner towards the top, away from where you’ve cut a hole for your head. Cover that hole with aluminum foil. Secure the foil with dark tape and poke a hole in the center of it with a pin.
Cover the inside of the front side of your box with white paper to make a viewing screen.
On a sunny day, stand outside with your back to the sun. Put on your pinhole hat so that the aluminum panel faces the sun and tilt and turn until a small circular dot is projected onto the white paper inside. If you need to, use additional dark tape to block any places where light is leaking into the box. You’re now ready for the day of the eclipse!
3. Found Object Projector
Any object with small holes will work similar to your pinhole projector. See the sunlight shining between those leaves or the holes in that colander above? During an eclipse, those objects will work like pinhole projectors. Simply look for a place where the sunlight shines through them and watch how the light changes* during the eclipse.
