Like the title says, I selected "drink all" from a canteen that was in my hands.

I quickly, and acidentaly, hit "6" on the mouse I have, and it swapped to the Binoculars on the hotbar. The animation played out, though, only I was drinking a pair of binoculars.

Yum.

It still said that I drank all the water in the Canteen, though, and my player was hydrated by it.

It left the Canteen hovering in the air in front of my character, afterwards. I was crouched through all of this.

The Canteen COULD be interacted with.
