4 ?

Take 5 piles and weigh them - if they're all good out and spend them

Take 3 piles from the 5 you have left - if they are good then add one of the 2 you have left. However if they do not weigh right take 1 off, and iff still no good take another off, at which point you can determine which is the right one.

So maximum of 4 weighs or if you're Eric Morecombe 4 Wheeeheyys.

What never gets any wetter no matter how much it gets rained on ?

A lake or other body of water, it's already 100% wet

A new riddle:

Many claim to seek me.
Most are angered if I rear my head unexpectedly.
Governments and religions claim to acknowledge me, (or sometimes to control me) but often try to hide me away.
Some people don't think I exist at all.
If everyone used me, the world might be a better place.
Despite my utility, my usage is considered rude.

What am I?

I'll invade your home and cross your floor
Kill me and I'm replaced with more
Taking your food to feed my brood
My presence is near-always booed
Utterly silent, just a speck
I will send your life to heck
With the power to madden without saying a word
I'll torment you singly or with my herd
Despite this its easy to send me away
And there's someone to do it if your willing to pay

What am I

Yes it was a lake or the sea or whatever -

What are you ?

The truth ?

No Honestly.

They go through pants but never wear them
They're often admired but no one will share them
Usually covered when running somewhere
When left in the open they pollute the air

What are they?

post 140 you have to weigh them once,
you take 1 coin from the first pile, 2 from the second and so on,and put them all on the scales
if the total is 10.7 for eg,then you know that pile 7 is the fake ones

Truth and feet were corrct answers, though not dust

Mould?

Post 145 - makes me think ants.

145 was ants.

Dunno if this qualifies as a riddle but, ....

I used this in D&D games. The party comes to a locked door which all their violence and spells fails to open, the pictograms on the door ask the question.

"What's the magic word?"

Please?

I suppose that 'what' is the magic word.

Did you nick that from 'speak "friend" and enter' from Lord of the Rings?

Gif

I never was, am always to be,
No one ever saw me, nor ever will
And yet I am the confidence of all
To live and breathe on this terrestrial ball

The future?

the future it was

The reply to what's the magic word was 'please' - remember your mum - "I wanna ice cream"
"What's the magic word darling ?"
