oil If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.
I am hot, sometimes soft, sometimes hard, sometimes runny and loose, sometimes I float, sometimes I sink but whatever form I take on I always go out and never in. What am I?
You can kill me but you can't eat me. You use me every day. I am always there. You cannot get away from me. If you can't manage me you must be disorganized.
What am I?
