Why does a spark occur when a person who is charged touches an uncharged object?

Near the charged object, there is a high charge, near the uncharged object a low charge. As you bring them together the gradient between the two gets steeper and steeper until it is strong enough to pull electrons away from the atoms in the air, ionizing it.
The ionized air conducts electricity better, making the gradient steeper still, and a chain reaction occurs. The energy stored is released in a sudden discharge, causing the heat, light and sound of the spark.
Lightning follows the same principle.

Why does electricity make hair stand up?
Electric charges in the hair can be attracted or repelled by an electrically charged object. When hair becomes charged with the same charge, it repels each other, causing the hair strands to stand up. This is known as static electricity.

Why do metals feel colder than wood when in same temperature and conditions?
Actually, the reasons metal objects often feel cooler than wooden objects has to do with the way the body feels heat and the rate metal conducts heat. If a room is left at 72 degrees Fahrenheit, all of the objects in the room will eventually reach 72 degrees, but a person standing in the same room will be at 98.6 degrees. When a person touches something in the room, he or she will be at a higher temperature than the object. Heat will flow from the hotter object (the wood or metal). The heat will flow through the wood or metal away from the person's skin, but at different rates, faster through the metal and slower through wood. We say then that metal conducts heat better than wood does. The end effect is there is less heat left in the finger where it touches metal than where it touches wood. The nerves in the finger sense the finger is cooler and the metal object seems cooler.
