Here is a source of small texts and videos in Luxembourgish that are probably not only interesting from the language learning point of view, but also if you want to learn something new and find out how things work. Some examples:
- Why don't we always grow higher and higher?
- Why should one inhale with a nose and exhale with a mouth while doing a sport?
- Why leaves are green and not black?
- Why money are not damaged in a washing machine?
Etcetera.
Double profit, I'd say. Note: some small portion of articles is in german...
