#HOW TO SEE THE ECLIPSE WITH CARDBOARD FREE#
However, it is ABSOLUTELY SAFE and FREE – no human being looks directly into the sun – or even comes into the temptation to do so.
It is correct – this emergency device can not completely replace the direct view. This is a completely cost-free natural experience, which we have already explained several times in past eclipse, in order to alleviate the panic in the country somewhat (happened in Germany 2015).
If then you continue using this self-made “emergency device for solar observation” during the eclipse as described above under 6, then any child looking only at the white paper can see the many “suns” during the duration of the eclipse look always “bitten off” in a different way! There are then no round suns anymore but a hundred small “sickles”. These appear perfectly round – just like a mini-sun. What you see projected onto the white paper are up to a hundred “tiny little suns” – projected images of the sun with a diameter of only 5 to 7 millimeters. The distances between carton and white paper do not have to be strictly adhered to! Try to hold the white paper so that the cardboard box with the “perforated” aluminum foil and the white paper are arranged parallel to each other. Shade the sun with the 40 x 40 cm cardboard so that the light of the sun falls from the sky – through the punched holes in the alufoil – onto the white paper. Next(while outside in the sun) hold the cardboard with the aluminum foil over a white A4 (Letter) paper sheet – with the aluminum foil in about 30 to 40 centimeters distance to the white paper. In this sturdy aluminum foil you can pierce 50 to 100 holes with a pin within the 10 x 10 cm cutout – the holes should be randomly distributed. Care is not necessary – no one looks directly into the sun by this arrangement !! The aluminum foil should have at least 15cm x 15cm (~ 6″ x 6″) edge length so that it is significantly larger than the rectangular hole cut into the carton. Place a layer of butterbread wrapping film made of sturdy aluminum (kitchen roll aluminum foil) over the hole with adhesive tape along the four sides of the hole. Approximately in the middle of the cardboard (or the carton piece) please cut a hole with roughly 10cm x 10cm (~ 4″ x 4″) edge length. part of a shipping box) – accuracy is NOT required cut a rough rectangle in the format ca 40cm x 40cm (~ 16″ x 16″) from a cardboard (e.g. Constructing a solar filter for binocularsīuild with your children a “CAMERA OBSCURA” (a lensless lens). #HOW TO SEE THE ECLIPSE WITH CARDBOARD HOW TO#
