The Hot and Cold Chimneys exhibit at the Exploratorium consisted of three copper pipes extended vertically from a cabinet: one cold, the middle at room temperature, and the last hot. I was able to play with how touching one pipe affected my perception of the other pipes. I placed my left hand on the hot chimney and my right hand on the cold one.

To what extent should we value information we draw from our senses?
Much of our knowledge of the world is gained through our senses of sight, hearing, touch and so on. Our information base is built from our use of sensory observations to learn a range of new material. With the inventions of telescopes, computers and microscopes were are able to continue to make new discoveries through the use of our eyes, ears, and sense of touch. Much of our knowledge seems to come from scientific observations, for example is why we now know of medicine that can be used to treat bacterial infections, due endless investigations with a microscope. It’s fair to say that a lot of our knowledge is based on experiential observations.
