Craftling — Water & Materials Waterproof Grotto

Hi!

I'm Craftling.

Welcome to Waterproof Grotto!

Will you help me investigate water & materials?

The Grumblies have mixed up our clues.

Let's check the evidence!

Absorbent materials take in liquid.

Waterproof materials resist water passing through under the conditions for

which they are designed.

Which material suits an absorbent pad?

  • A. The cloth
  • B. The water-resistant coated sheet
  • C. A sealed glass cover

The answer is A: The cloth

Our equal-water test shows cloth soaking up water

and a coated sheet keeping the surface beneath dry.

Cloth suits an absorbent pad;

the sheet suits the tested cover.

That clue helps us make sense of this place.

Porous materials have spaces, but how water behaves depends on the material

and its structure.

Use test records rather than guessing from looks.

Which suits the tested rain cover?

  • A. The soaking cloth
  • B. An open mesh that lets rain through
  • C. The coated sheet

The answer is C: The coated sheet

Our equal-water test shows cloth soaking up water

and a coated sheet keeping the surface beneath dry.

Cloth suits an absorbent pad;

the sheet suits the tested cover.

Hmm...

how does that connect to our first clue?

Our equal-water test shows cloth soaking up water

and a coated sheet keeping the surface beneath dry.

Cloth suits an absorbent pad;

the sheet suits the tested cover.

What does absorption mean?

  • A. Turning liquid into air
  • B. Taking in liquid
  • C. Always blocking liquid completely

The answer is B: Taking in liquid

Absorbent materials take in liquid.

Waterproof materials resist water passing through under the conditions for

which they are designed.
