What Am I Riddles

I am lighter than air but a hundred people can’t lift me. Careful, I am fragile. What am I?

I am the type of room you can not enter or leave. Raise from the ground below. I could be poisonous or a delicious treat. What am I?

I can be long or short. I can be grown or bought. I can be painted or left bare. I can be round or square. What am I?

I can be cracked, made, told and played. What am I?

I am gentle enough to soothe your skin, light enough to fly in the sky, strong enough to crack rocks. What am I?
