Perfect glass

Welcome, if you are tired of coincident surface in your non opaque fluid containers, it might be the right place.

An easy test, as multiple-choice questions, to check the lesson of today:

  • How do you make an empty plate ?
    1. You select a material, a shape and combine both.
  • How do you make an empty glass ?
    1. You select a material, a shape and combine both.
  • How do you put a cake on a plate ?
    1. Take the plate and and move the cake to the plate.
  • How do you fill a glass with a liquid ?
    1. Take the empty glass and pour the liquid, well put the liquid in a suitable shape and move it to the glass.
    2. Mu. This is a non-sense.

The right answer is 2: to achieve a glass with some liquid, you should not start with an empty glass.

If you start with a filled glass, you might end with an empty glass. But the reversal is bogus: you would get coincident surface and its noise.
