Answer:
I bring light to a dark world. In a current I travel and through tunnels I am hurled. Touch me and I'll kill you. What am I?
Though it be cold I wear no clothes the frost and snow I never fear; I value neither shoes nor hose And yet I wander far and near: My diet is forever good I drink no cider port nor sack what Providence doth send for food I neither buy nor sell nor lack.
When you buy me I am costly, but the only use I have is hanging only. What am I?
I make a loud sound when I'm changing. When I do change I get bigger but weigh less. What am I?
I can be thin but not fat; in your body but never on your placemat. I'm always better when I'm fresh but you'll never see me in the flesh.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
