✍️ Poem about Reaction

Ein Stein fällt in den stillen Teich,
die Wellenkreise folgen gleich.
Ein Wort gesprochen, laut und klar,
erzeugt 'ne Antwort, wunderbar
oder auch mal schroff und kühl,
die Reaktion, ein Wechselspiel. Ob Mensch, ob Stoff, ob Tier, ob Baum,
auf Aktion folgt sie im Lebensraum.

Translation:
A stone falls into the silent pond,
the ripples follow right beyond.
A word spoken, loud and clear,
creates an answer, wonderful, dear
or sometimes harsh and rather cool,
the reaction, an interplay, a rule.
Be it human, substance, animal, or tree,
upon action, it follows, for all to see.

🧩 Little Riddle

Ich folge stets auf eine Tat,
bin Antwort, Wirkung, Resultat.
Mal chemisch bunt, mal nur ein Laut,
mal heiß ersehnt, mal kühl geschaut.

Was bin ich?

Translation:
I always follow an action or deed,
I'm response, effect, result indeed.
Sometimes chemically colorful, sometimes just a sound,
Sometimes eagerly awaited, sometimes coolly found.

What am I?

Solution: die Reaktion (the reaction)
