Yesterday I posted some videos on Instagram of step-by-step instructions on how to build your own pinhole projector to safely view the eclipse on August 21st. In order to make the instructions easier to share, I’ve compiled them all here (well, screenshots from them at least) to help you turn an ordinary cardboard box into a pinhole projector.
For more information on the eclipse check out the NASA website eclipse2017.nasa.gov.
Step 1: Find a cardboard box and cut a white piece of paper to fit the bottom.
