Who doesn\u2019t love a good solar eclipse, especially when it happens while you\u2019re cruising the world with Holland America Line?<\/a>\u00a0If you\u2019re an eclipse enthusiast, then you don\u2019t want to miss our 22-day Solar Eclipse Cruise<\/a> aboard the Koningsdam for the total eclipse on April 8, 2024. In the meantime, consider satisfying your astronomical wanderlust during the upcoming annual eclipse on Oct. 14 with a fun activity at home.<\/p>\n We recently caught up with University of California San Diego (UCSD) Professor of Astronomy and Astrophysics Adam Burgasser \u2013 our featured guest speaker on the Solar Eclipse Cruise \u2013 and the UCSD Cool Star Lab to learn how we can make our own eclipse viewers with household materials. Here\u2019s what you need to get started:<\/p>\n<\/div> 1. Glue down a piece of white paper onto one of the inner sides of the box. The best side is at the end of the longest side of the box.<\/p>\n<\/div><\/div><\/div> 2. Remembering which side you covered in white paper, seal up the box using tape to cover up any gaps along the box edges. Make sure the inside of the box is as dark as possible.<\/p>\n<\/div><\/div><\/div> 3. On the opposite side of the box from your white paper, cut two openings about 2-3 inches across, and ensure they\u2019re well separated.<\/p>\n<\/div><\/div><\/div> 4. Cover one of the holes with a piece of aluminum foil. It’s best to use tape as aluminum foil doesn’t work well with glue. Now poke a single small hole in the aluminum foil with a pushpin, paper clip, or toothpick. This is the pinhole for your pinhole viewer.<\/p>\n<\/div><\/div><\/div> With the sun behind you, position your box so that the side with the hole and aluminum foil points back at the sun. You may need to tilt and move the box around to get things lined up, but you should see a small image of the sun inside your box when looking in the hole. This is normally round, but during an eclipse you will notice a crescent shape.<\/p>\n And there you go! Eclipse viewer magic.
