"Tuinkers bakfiets" - the "cress bike"

This coming sunday, we have the "Cultural Sunday" here in town and the theme is "City oasis".
I was asked to take part and created the "Cress bike" for that day, a bike with all the supplies to enable people to make their own pot with cress seeds. You can then take it home and let it grow.
It's sooooo simple and easy to make your own vitamines and you can use it for all different sorts of food: in salads, on bread, with joghurt...
