The goal is to cover the blue message enough that it is no longer readable to the naked eye. The red ink should look like a chaotic jumble of lines or shapes.
Place your red decoder lens over the paper. The red filter will make the red marker "disappear" into the background, while the blue or green text will appear dark (nearly black), making the secret message clearly visible. Alternative Method: Invisible Ink DECODE RED - Part 222:26 Min
One light blue (or green) marker and one bright red marker. The goal is to cover the blue message
Red cellophane paper or a transparent red plastic sheet. Scissors and Tape/Glue: To create the "decoder lens". Step-by-Step Instructions Prepare the Decoder Lens (5–10 Mins) The red filter will make the red marker
Cut a piece of cardstock into the shape of a magnifying glass or a simple rectangle with a hollow center.
On a separate piece of white paper, write your secret message using a . Keep the letters clear and thin. Create the "Red Noise" Camouflage (10 Mins)
To create a "DECODE RED" activity—a popular project where a hidden message is revealed using a red filter—follow the steps below. This activity is designed to take roughly to complete. Materials Needed Paper: White construction paper or cardstock.
Financial support for Rubin Observatory comes from the National Science Foundation (NSF) through Cooperative Agreement No. 1258333, the Department of Energy (DOE) Office of Science under Contract No. DE-AC02-76SF00515, and private funding raised by the LSST Corporation. The NSF-funded Rubin Observatory Project Office for construction was established as an operating center under management of the Association of Universities for Research in Astronomy (AURA). The DOE-funded effort to build the Rubin Observatory LSST Camera (LSSTCam) is managed by the SLAC National Accelerator Laboratory (SLAC).
The National Science Foundation (NSF) is an
independent federal agency created by Congress
in 1950 to promote the progress of science. NSF supports basic research and people to create knowledge that transforms the future.
NSF and DOE will continue to support Rubin Observatory in its Operations phase. They will also provide support for scientific research with LSST data.
