You must have been using things like glue and fevicol for your arts and crafts since childhood, but have you ever wondered why glue dries when it comes out and remains sticky when it stays inside? Today we are going to tell you how gum or fevicol stays inside the bottle without sticking. For this we first need to know what gum is and how it is produced. What are the things mixed to make it?

Actually, chemicals like polymers are used to make gum. Gums can be very sticky and stretchable by the polymer strands. Similar polymers are used when making glue. Water is also used in this, due to which it becomes slightly wet. Water liquefies the glue and acts as a solvent. The gum does not dry with water, but when the gum is taken out of the bottle it is exposed to air and completely dehydrates it through steam.

After this, the glue is left with only the polymer and becomes sticky and stretchy again. When the glue bottle is closed, the water inside does not come in contact with the air and then does not dry, so the glue in the bottle does not dry. Now you must have noticed that if the bottle of glue is left open, it dries up immediately and is of no use. That’s why always keep the lid of the glue bottle closed.
