For me, much blood has been shed. I have two faces but only bear one head. What am I?

Sometimes I fly as fast as the speed of light. Sometime I crawl as slow as a snail. Unknown until I am measured but you will certainly miss me when I'm gone. What am I?

I sleep by day and fly at night, but I have no feathers to aid my flight. What am I?

I am not alive and yet I grow. Just put me next to where it grows. A favorite of the summertime, best with friends when combined. What am I?

I can fill a house or fill your mouth but you can never catch me in your hands. What am I?

I fly in the air without engines and I am controlled by man on the ground. What am I?

I let water fall on you while everyone else stays dry. What am I?

I am a box who holds keys but not locks. With the right combination I may unlock your soul. What am I?

I am alive without breath and cold as death. I am never thirsty but always drinking. What am I?

Most people love to use me. You make me glide through the air. Even your dog loves me. What am I?

I get paid to shoot people, then blow them up. What am I?

I shift around, though always slowly. I never move more than a few inches at a time. A large movement by me can kill many people. I am huge, yet unseen by humans. What am I?

I am a daily ritual involving using a metal tool on the body. What am I?

I do not eat food. But I do enjoy a light meal everyday. What am I?

You can throw me away, but I will always be coming back. What am I?

I am the kind of food monkey likes, and people slip on me and fall in cartoons. What am I?

Hide me from your parents if you have done bad academically this year. What am I?

A hand without flesh and nothing can I hold. My grip cannot be used until I am sold. What am I?

I help engines spin and pants stay up. What am I?

Black within and red without, With four corners round about. What am I?
