A man is found hanging from the ceiling in a locked room.
There’s nothing in the room except for a puddle of water beneath him.
How did he die?

I have no mouth, yet I carry the weight.
I never move alone,
But I changed how you travel—and your fate.
What am I?

When I’m used, I’m useless.
Once offered, soon rejected.
In desperation, I’m often expressed.
What am I?

I am always hungry and need to be fed,
But whatever I touch will soon turn red.
What am I?

I don’t burn, but I illuminate.
I’m silent, yet I show the unseen.
I bring clarity, but never speak.
What am I?

My point is sharp,
But I cause no pain.
I speak silently, and people listen.
What am I?

My edges are sharp,
But I need both sides to work.
I’m useless alone.
What am I?
