Fluency in a language learning context is not the same as native speakers. The measure is can you pass a 4th grade grammar class in the given language.

My understanding is that you won’t get fluent but it would give you up to a middle school level understanding, depending on the language. French and Spanish were more advanced than Mandarin or Welsh.

I don’t think I’ve ever run into anyone else who has seen or remembers surf ninjas. What a great fever dream of a movie.

Chemicals react with different materials differently. I’m not a chemist but there are probably plenty of chemicals that would react with the stainless steel or paint of a tesla but not the rubber in a balloon. Bleach and ammonia off the top of my head would probably mess up the trim pretty good. Doesn’t have to burn holes to do damage.
