I am weighing a cp of water and putting the tip of my finger in it without 
touching the bottom and not applying any force but the weight on the scale 
increases. The experiment is simpe but the reason behind it is somewhat 
puzzling. The amount of water does not change and it is relatively undisturbed. 
What happens?
