The black ribbon


Black cotton ribbon rolled up on a beech wood pin.
The fabric is 46 meters long which means 4.6 billion years of geological history.
At the end of the black strip there are 2 cm of red fabric which represents the existence of people on Earth.
Epoch and period markers are sewn along the ribbon in the colors of the official color scheme of the International Commission of Stratigraphy.

The child learns with all senses how long the development of the earth and mankind took.
