German:
Unsichtbar, doch voller Kraft,
Die Druckluft, die so vieles schafft.
Sie treibt Maschinen, füllt den Reifen,
Lässt Werkzeug zischen, bohren, schleifen.
Komprimiert in Kesseln klein,
Setzt Energie blitzschnell frei.

Compressed air, achieving much outright.

Makes tools hiss, drill, grind higher.

Releasing energy with rapid light.
