✕Common Mistakes
Le tube sont vide.
The verb must agree with the singular subject "le tube"; use "est" not "sont".
La tube est vide.
"Tube" is masculine, so the correct article is "le".
Oui, le tube est vide.
While grammatically correct, using "Oui" instead of "Ouais" changes the register from informal to neutral.

Cultural Tip
"Ouais" is very informal; avoid it in formal writing or when speaking to authority figures. Also, note that "le tube" can be slang for a hit song, so context matters—here we’re talking about a literal tube, not music.
