7th advent door

Welcome to the advent calendar of LernLaborFarbe. Every day for the next 24 days you will find a little video about color and light.

Today it starts: 7. Adventstürchen (external link)

Today we have an experiment for you to participate in. With the help of #chromatography, you can show what mixture the color of the black felt-tip pen consists of.

You need:
- filter paper (coffee filter, kitchen paper, ...)
- black felt pen
- scissors 
- kitchen paper
- glass/ mug with water

You can see the exact procedure in the video. 
If you like, you can also try the experiment with other colors. 

The team of LernLaborFarbe wishes you a lot of fun!
