Question

Is "I'm drinking a flask." grammatically correct like "I'm drinking a soda."?

Answer 1

Answer: No!

Explanation:

Flask is a container for liquids. It's not a liquid but a container for a liquid and you don't drink a container so no.

Hope this helps :)

Answer 2

You cannot drink a flask thus it is a container only but you can drink what is in the flask. You could say “I’m drinking the soda Inside the flask”
