What is the principle of chewing gum opening coconut?

Coconut is a tropical fruit and is very special because it is very large and the main edible parts are the juice and pulp inside the shell. However, the shell is very hard and difficult to open by human power. Therefore, opening coconuts is also a very laborious and technical job. Many people are surprised that scientists can use chewing gum to open coconuts. Let’s take a look at the principle of using chewing gum to open coconuts. Let’s take a look at the explanation below, I hope you can understand something.

Although coconut juice tastes good, its shell is very hard, and you often need to use a knife or an axe to split it open or drill a hole in it before you can drink the coconut juice. But if you've just eaten a piece of gum, you can use it to drill a hole in the coconut.

According to the properties of non-Newtonian fluids, when the external force on a non-Newtonian fluid increases and the speed increases, it will become very hard.

So if you want to use chewing gum to crack a coconut, you can make the chewed gum into a pointed cone, and then smash the coconut against the chewing gum hard and quickly. The pointed cone-shaped chewing gum will be hit by the quick and huge force of the coconut and become a hard weapon, which will also crack the coconut.

Chewing gum can open coconut shells because it uses the principle of non-Newtonian fluids. This is because non-Newtonian fluids have the characteristic of becoming stronger when faced with strong impacts.

Non-Newtonian fluids are relative to Newtonian fluids and are widely present in life and nature. The vast majority of biological fluids belong to the non-Newtonian fluids defined today. Various body fluids in the human body, such as blood, lymph, cystic fluid, and "semi-fluids" such as cytoplasm are all non-Newtonian fluids.

According to the properties of non-Newtonian fluids, when the external force a non-Newtonian fluid is subjected to increases and the velocity increases, it will become very hard.

The above is an explanation of the principle of using chewing gum to open a coconut. The principle is very simple, but ordinary people should never imitate it to avoid causing unnecessary trouble.
