"And what happens if we do not push it?"

Translation: Und was passiert, wenn wir es nicht drücken?

[Soglio]

Could "stossen" work here? "Drucken," I thought, meant "press" rather than "push." The two are sometimes synonymous in English, but not completely.

[Vindalf]

Well drücken is always written on doors in Germany that you need to push to open, so it's probably the better choice for "push"

My answer: "Und was passiert wenn drucken wir es nicht?"
Why is it wrong?

"Wenn" begins a relative clause, so the verb goes to the end:
