Always in you, Sometimes on you;

If I surround you, I can kill you.

What am I?

I am dry when I go inside, but wet when I am pulled outside.
The longer I am inside, the stronger I get
When I am completely out, I am wet and I literally sag
Who am I?

Begin with a word, five letters to my name,
Remove the first and last but I am the same
Take out my middle and still, I remain.
What word am I?

I don't get anymore wetter, no matter how much rain falls on me.

One day, John and his friends were playing around. Jacob hit something with a Pin and it popped. John's dad came into the room that very moment, but he wasn't mad. In fact, he was smiling. What did Jacob hit?

John enters a small room. The Door Closes.
When the door opens, John is in a larger room.

Without looking at a calendar, within a minute name, a boy's name using 5 consecutive 1st letters of 5 consecutive months

The more of this there is, the less you see. What is it?

What has six faces, but does not wear makeup, has twenty-one eyes, but cannot see?

What has to be broken before you can use it?
