Below are several safe viewing methods that you can try depending on what materials are available to you. Try them out on a regular sunny day to practice so that you are ready once the big eclipse day comes around.<\/p>\n<ul>\n<li>Use two pieces of stiff white cardboard (paper plates will do) to <a href=\"https:\/\/www.timeanddate.com\/eclipse\/make-pinhole-projector.html\">make a simple pinhole projector<\/a>;<\/li>\n<li>Use a cereal\/cookie box, paper, and aluminum foil to <a href=\"http:\/\/astroedu.iau.org\/en\/activities\/1409\/safe-sun-viewer\/\">make a pinhole viewer<\/a>;<\/li>\n<li>Use a small mirror inside an envelope to <a href=\"http:\/\/www.eclipse.org.uk\/old\/pparc_web\/mirror.html\">reflect an image of the Sun on to a screen<\/a>;<\/li>\n<li>If you have binoculars that can be mounted on a tripod, <a href=\"https:\/\/www.space.com\/15995-safe-sun-projector-binoculars.html\">use them to project the Sun\u2019s image on to white cardboard<\/a> (<strong>CAUTION<\/strong>: do not look through the binoculars while they are pointed at the Sun and beware the heat that will be generated near the eyepieces. Give your binoculars breaks from being focussed on the Sun every few minutes so that they don&#8217;t overheat. <strong>Do NOT leave this apparatus unattended!<\/strong>)<\/li>\n<li>Buy your own eclipse glasses.
