Answer:
A home of wood in a wooded place, but built not by hand. High above the earthen ground, it holds its pale blue gems. What is it?
I move without wings, Between silken string, I leave as you find, My substance behind.
What goes in the water black and comes out red?
So cold, damp and dark this place. To stay you would refrain, yet those who occupy this place do never complain.
I bind it and it walks. I loose it and it stops.
Why is the letter B always cool?
