Project the farmer's best helper
We filled two Norwegian glasses in layers with soil and sand with 3 marks in each layer. On top we put a layer of grated carrot. We have followed and checked whether anything has happened in the glasses for several weeks.
Gradually we saw carrot far down in the glass. After three weeks all the carrot salad was gone, the fields had been made many times in the soil and mixed soil and sand. Exciting to see!
