Why do marshmallows grow larger in a vacuum?

Marshmallows are porous structures that contain a certain amount of air. In a vacuum state, this part of air expands and drives the marshmallows to expand. From the kinetic theory of molecules, we know that the pressure of a gas is generated by a large number of molecules frequently colliding with the container wall. The collision time of a single molecule on the container wall is extremely short, and the effect is discontinuous, but a large number of molecules frequently collide with the container wall, and the force on the container wall is continuous and uniform. The ratio of this pressure to the area of ​​the container wall is the pressure.

What is the temperature for making marshmallows?

It is about 185 degrees. 185 degrees is the temperature at which white sugar melts. The temperature for making marshmallows is not high. You just need to melt the sugar, and then rely on the rotation of the machine to wrap the sugar threads into cotton shape.

Marshmallow is a kind of snack food. In the market, on the street, especially near the school, you can often see small vendors pushing bicycles or tricycles carrying marshmallow making machines to make marshmallows on the street. A spoonful of sugar is put into the simple machine that rotates quickly, and then around the machine wall, layers of white "silk thread" are wrapped around the small stick, and soon it becomes a ball of snow-white fluffy marshmallow. Marshmallow tastes sweet and sticky, especially loved by young people and children. Marshmallow has many flavors, including strawberry, sweet orange, grape, banana, pineapple, mint, blueberry, etc., colorful and very beautiful. It has a loose taste and does not stick to the teeth. Due to its low sweetness, it is suitable for rest or after meals.

Characteristics of Marshmallow

Marshmallows are a very different type of hard candy, consisting of very fine strands of sugar glass, similar in texture to cotton balls, which melt as soon as they are put into your mouth. Marshmallows are made using a special machine that forces the molten sugar through a tiny spinning nozzle, where it solidifies into sugar strands as soon as it comes into contact with air. This machine was first introduced at the 1904 St. Louis World's Fair.
