The first thing that happens when you touch something hot is the activation of specialized nerve endings called thermoreceptors in your skin. These thermoreceptors detect the change in temperature and send a signal to the brain through the neuron to alert you of the heat and trigger a reflex action like pulling your hand away.
The neuron in your finger senses the temperature first. It sends a signal to your brain, which then interprets the information and signals your muscles to move your hand away from the heat source.

Heat transfer occurred from your finger to the cold water, as heat moves from a higher temperature region (your finger) to a lower temperature region (the water) in an attempt to reach thermal equilibrium.
When you take your finger off the top of a straw, the atmospheric pressure pushes the water up the straw to fill the empty space created by your finger. This is due to the difference in pressure between the top and bottom of the straw.
Sliding a finger up and down the nose can be a sign of contemplation or deep thought. It may indicate that the person is thinking deeply about something or is trying to make a decision.
