What does 緊張感{きんちょうかん} in this sentence mean?


I am reading Yotsubato! ([Link](http://raw.senmanga.com/Yotsubato!/82/3))
manga (Ch.82, Pg.3) in Japanese. I came across this sentence:

> このフタは緊張感{きんちょうかん}がある。

So far I have searched and the only meaning I came across is tension,
nervousness etc., What I think is, the character looks at the plate (lid) in
front of him and says that he is nervous because the plate doesn't have flat
surface and it wobbles. But when I try to translate it into English,

> このフタは (as for this lid) 緊張感{きんちょうかん} (nervousness) がある (exists)

Excuse my translating if it's not correct (I'm a beginner) but what I
understood is, he is somehow feeling nervous about this plate or the plate is
making him tense. What confuses me is the last part [がある].

If I am correct so far, this would mean something like, as for this lid,
nervousness exists ? This is confusing me. Is this natural way of saying that
something makes you feel nervous ?




Yes, it's obvious from the context that the sentence basically means "using
this lid (as a plate) requires me to tense" because it wobbles.

緊張感がある (or, more commonly, 緊張感が漂う) may be used with something like 教室 or
2人の関係, but usually not with a フタ. The sentence is definitely said in a
comical, playful way. The "serious" version would be something like
このフタを使うには緊張感が要る, but it would be less funny. Don't try to analyze this
sentence too seriously.
