1. There is no air inside of the tube, therefor it does not harden. Yet, if you allow air to get into the tube.. it will harden even inside.. 2. Anything that gets darker because of water would have to do with the change in the item by way of seepage and the absorption of the liquid. 3. That has much to do with the fact that we are looking up at the sky, and not down on it. 4. Blind people can see their dreams, and there is a difference between one that was born blind and one that was blinded later in life.. it differentiates, they way they perceive their dreams.. 5. Insulation of the body.. and something to do with external heat pushing in rather than the inner one pushing out..
