So I have done a couple of personal experiments with water on my hands. One day I was taking bread (rolls to be exact) out of the oven with my bare hands and burned my hands when my hands were dry. Then a couple days later my hands were wet and took them out and did not feel pain and did not feel like I had to let go of the rolls for about 3 to 4 seconds.
Another "Experiment" that I had was I had was I wet my hand with saliva and put it above the flame of a candle and I lasted about 3.6 seconds and my friend lasted less than a second. My question is why can I touch things longer when my hand are wet?
