The Hobbit: Riddles in the Dark

Bilbo, lost in the caves of the Goblins, stumbles in the dark to the edge of a subterranean lake.  There he meets a creature called Gollum.  Gollum intends to eat Bilbo, but Bilbo challenges him to a Riddle duel.  If Bilbo can't answer a riddle set by Gollum, then Gollum will kill and eat him; if Gollum can't answer a riddle set by Bilbo, then Gollum must show Bilbo the way out of the Goblins' caves.

How would you do?  How many of these riddles can you solve?

1. What can you catch but not throw?
2. What is in seasons, seconds, centuries and minutes but not in decades, years or days? 
3. Inside a burning house, this thing is best to make. And best to make it quickly, before the fire's too much to take! ...  
4. I am related to the water, but I am not wet. I am an illusion, but I show what is real. What am I?  
5. What goes first but then follows? What fills in holes and blocks out the sky? What hides shadows, but runs from the sun?  
6. I have holes on the top and bottom. I have holes on my left and on my right. And I have holes in the middle, yet I still hold water. What am I?
7.  If you have it, you want to share it. If you share it, you don't have it. What is it?
8. I am the beginning of the end, and the end of time and space. I am essential to creation, and I surround every place. What am I? 
9. I am all about, but cannot be seen.  I can be captured, but not held.  I have no throat, but I can be heard.

Do not post your answers; instead, type them up with a title and a footer (all Golden rules..) in MS WORD and print them off.  Leave them on the printer.  I will collect them later.
