I resemble a suction cup, but I do not suck. You can prevent flooding with me.

My first half sizzles and crackles with heat, My second is gone, or a truth you repeat. Join them together, the story is plain; A fire snuffed out and a tired brain.

I have a deck, but I don't have a mast. I am often seen in half-pipes.

I am deadly to consume, but you may find me in a traditional home. when a certain skeleton saw me in this traditional way he became perplexed, what am I?

An unblinking judge, glowing with borrowed light. It shows the world through a window, but cages that world in glass.
