The SOS Jar is a jar with a switch on the top of the lid. The project consists of an Adafruit Circuit Playground Express (CPX), 2 alligator clips, a switch, a foam sheet, a AAA battery pack, and lastly a jar.

When the switch located on top of the jar is turned on. The CPX inside the jar will light up with rainbow colors. The CPX will also use its soundboard to play morse code for "SOS".

The SOS Jar is designed to be used by people at sea. When a distress signal is needed, the user can turn the SOS Jar on and then let the jar drift in the sea. Or the jar can be held up as a source of light for others to see in the distance.
