Cool things a Thief can do with their bonus action

[Slybluedemon]

What cool and clever thing would you do with the Thief's "Use an Object" bonus action?

Throw dust in someone's eyes?
Splash Acid?
Drink Liquor in a fight?

[No brains]

Drinking liquor in a fight is explicitly called out as an object interaction, though one that calls for a constitution check. (PHB 177 and 190)

[Trask]

Obligatory healing kit mention. With the Healer feat that becomes quite potent.

But use of alchemists fire, acid, burning oil, all of these things and more can be yours.
