My head and tail both equal are,
My middle slender as a bee.
Whether I stand on head or heel
Is quite the same to you or me.
But if my head should be cut off,
The matter’s true, though passing strange
Directly I to nothing change.
What am I???
Are you having the two riddles being puzzled over at the same time? Or are you going to let me stay at least half sane by letting us know the solution to the first one? 
Yes 
Sorry, someone answered it a whle ago, in pm, I thought everyone else gave up. I can pm answer or just post it, whatever’s clever.
(edit)
Alright, the answer to the tea riddle: There was poison in the ice cubes. The one that drank it fast didn’t let the ice melt. The ice melted into the slow brother’s cup, and he drank the poison.
Are you the letter “I”
nope, the letter I, cut is not nothing. its, still the letter I
Are you the number 8? 
Where can you find roads without cars, forests without trees, and cities without houses?
in an LD 
Good guess, but no. Its not that hard if you think about it.
Nowhere?
No.
Answer to my riddle: Yes, I am an 8.
Wizard: A map?
Yes, Archrin, the answer is a map.
I know i’m just being a nitpicker here, but there are houses on maps, at least in the Melways everone uses in Melbourne. And whose to say that blobs of green ink are forests. 
Good work on keeping this topic alive though. 
I’ve now got a riddle.
It was a hot summers day with the sun directly overhead, and an eagle flies by (not up or down). You look down at the shadow and are surprised to see that it is a round circle moving across the ground (note: this is the shadow, not some grey creature).
The question is why is the shadow round? And i must tell you that the answer is silly or no one will get it.
Is it your own shadow, or is the bird carrying and unbrella?
Silly eh? The eagle was really a sphere! The only thing i can think of is that its not the eagles shadow but is really like a baseball… or maybe eagle is australian slang for ball…
oops i forgot to check this topic. †Archrin† is right it is an umbrella that the eagle is holding! Did you already know this?
hehe, but good try.
does anyone else have any more riddles?
No, I didn’t already know it, but for some reason it popped into my head.
Riddle:
Light as a feather, there is nothing in it;
the strongest man can’t hold it
for much more than a minute.
What is it?
is it air, and he can’t hold his breath for a minute
i put my guess small so other people can also guess.
