ii. Touch the water in each cup with the tip of a finger to verify the temperature of each.
iii. Put your left index finger into the hot water, and your right index finger into the cold water.
iv. Leave your fingers in the cups for at least 30 seconds. What happens to the sensation in each finger as time passes?
v. After at least 30 seconds, quickly move both of your index fingers into the room-temperature water in the middle.
