I'm a specialist in the field of material science, with a focus on polymers and their behavior under various conditions. Let's delve into the fascinating world of chewing gum and the process that leads to it becoming hard when exposed to water.
Chewing gum is a complex mixture of various ingredients, including a polymer known as the gum base, which is responsible for the chewiness and texture of the gum. The gum base is typically a blend of synthetic rubbers and natural polymers like polyisobutylene and polyvinyl acetate. These polymers are responsible for the elasticity and tensile strength of the gum.
When you chew gum, you're not only breaking down the sugar and other flavorings but also warming up the gum base with the heat from your mouth. This warmth increases the mobility of the polymer chains, making the gum more pliable and easier to chew. The gum base is sensitive to temperature, and this sensitivity plays a crucial role in the hardness you experience when you drink water.
Now, let's discuss the process step by step:
1. Chewing and Warming: Initially, as you chew the gum, it becomes warm and soft due to the heat from your mouth. The polymer chains in the gum base move more freely, allowing the gum to stretch and deform.
2. Drinking Cold Water: When you drink cold water, you introduce a sudden change in temperature. This cold water cools down the gum base rapidly.
3. Temperature Sensitivity: The gum base is highly temperature-sensitive. As it cools, the polymer chains slow down and become less mobile. This reduced mobility means the gum loses its pliability and becomes stiffer.
4. Stiffening: The rapid cooling causes the gum to stiffen because the polymer chains can no longer move as freely as they did when warm. This is similar to how many materials become more brittle at lower temperatures.
5. Re-warming: If you continue to chew the gum after drinking water, the heat from your mouth will gradually re-warm the gum base. As it warms up, the polymer chains regain their mobility, and the gum becomes soft and chewy again.
It's important to note that the hardness you feel is not due to the water itself but rather the temperature change that the water induces. If you were to drink room-temperature water, you might not notice as significant a change in the gum's texture.
In conclusion, the gum gets hard when you drink water because the cold water rapidly cools the gum base, reducing the mobility of the polymer chains and causing the gum to stiffen. This is a direct result of the gum base's sensitivity to temperature changes.

So if you have a piece of bubble gum in your mouth and you drink cold water, or you crunch a piece of ice, what you are doing in changing the temperature of the gum base. Since the gum base is so sensitive to temperature, it gets stiff. Then, once you warm the gum up again in your mouth, it gets soft.
