Glass Goblet

If a piglet is a small pig, and a droplet is a small drop, I guess a goblet is a small gob. Which is British and Australian slang for "mouth". So maybe you need a small mouth to drink from a goblet.

Amazingly, you can start with a cube in Blender, and end up with no straight lines anywhere. It has this thing called sub-surfaces. You give it a cube with 6 faces, tell it to sub-surface, and it turns each face into 4 faces. Which arrange themselves to halve the angles between the faces, so you end up with something rounder. Which sounds like the result after eating at McDonalds for too long.

If you sub-surface to level 2, you get each of the sub-surfaced faces sub-surfaced as well, so the 4 faces then becomes 16 faces. And you can sub-surface to level 3, 4, 5, etc. Each time the result is smoother than before.

Each part of this goblet was a cube, or something vaguely cubish (not cubist, that's those crazy painters from last century like Picaso). The stem and part you drink from was a very tall tube (or a "skinny" one if you don't mind being politically incorrect).

Ray-tracing comes in handy here again, not this time for reflections but for refractions. Like when you throw a spear into a lake to catch the fish but it misses by six inches cause the light has been bent. Until you adapt and aim 6 inches away from the fish. Clever human.

The base looks a bit too small, but I think that's an optical illusion from the perspective. In Blender you can view the scene in Orthogonal (straight-on) or Perspective mode, where things closer to you look bigger. Like that exam you haven't studied for tomorrow.
