Pouring Beer: Catfish Bait Or Urban Myth?

Pouring coke, mentos, and eggs into a catfish hole is a fishing technique that causes the fish to leave their holes. The egg lures the fish to the entrance of the hole, while the combination of mentos and coke creates an environment rich in carbon dioxide, which repels the fish.

The egg lures catfish to the hole

Catfish are known for their sharp sense of taste and their willingness to take a wide variety of bait. They are also known to surface for air when there isn't enough oxygen in the water.

The egg is used to lure the catfish to the hole. The dominant theory is that the catfish are attracted by the egg and swim into the hole. The egg acts as a lure, enticing the catfish to come closer and investigate. Once they are close enough, they can be caught using various methods, such as by hand or with a net.

While the effectiveness of eggs as catfish bait has not been tested in a lab setting, it is clear from the viral video and various comments that eggs are an effective way to attract catfish. The egg's scent and taste are likely what draws the catfish in, as they are curious creatures with a well-developed sense of taste.

In one version of the video, the man adds Coke and Mentos to the hole after the egg. The carbon dioxide produced by the reaction between the Coke and Mentos creates an oxygen-poor environment, causing the fish to panic and try to escape. This further entices the catfish to come closer to the hole, making them easier to catch.

While the video may be staged, as some have claimed, the science behind the use of eggs as a lure for catfish is sound. Catfish are attracted to a variety of baits, and the protein-rich egg is an effective lure that can be used to attract and catch these fish.

Mentos and Coke create an CO2-rich environment

The combination of Mentos and Coke creates an eruption of foam and bubbles, a phenomenon known as the Mentos geyser effect. This occurs due to the rapid release of carbon dioxide (CO2) from the carbonated soda, resulting in a dramatic display of foam and bubbles. The surface of Mentos candies is rough and covered with tiny pits or nucleation sites, which provide an ideal location for CO2 bubbles to form. When dropped into a carbonated liquid like Coke, these pits facilitate the gathering and formation of CO2 molecules into bubbles.

The physical reaction between Mentos and Coke involves both physical and chemical changes. The physical change occurs when the Mentos candy interacts with the Coke, providing nucleation sites for carbon dioxide bubbles to form. This leads to the visual spectacle of the eruption. Simultaneously, chemical changes also take place. As the CO2 bubbles form on the Mentos surface, they undergo gas solubility, moving from the liquid phase to the solid phase of the candy. This process causes the CO2 bubbles to increase in size as they flow towards the candy's surface.

The Mentos and Coke reaction is not due to a complex chemical interaction but rather basic principles of surface tension and nucleation. The rough surface of Mentos candies amplifies the agitated motion of the liquid, increasing the likelihood of bubble formation. Additionally, the ingredients in Mentos, such as artificial sweeteners like aspartame, help reduce surface tension, further facilitating bubble formation.

The Mentos and Coke experiment has captivated audiences worldwide and is often used by educators to explain scientific principles in an engaging way. It provides a simple yet impressive demonstration of the underlying physics and chemistry involved in everyday materials.

CO2 causes the catfish to leave

The method of pouring beer into a catfish hole is a clever way to create a CO2-rich environment that encourages the fish to leave their hiding spots. This technique is particularly useful when fishing in areas with dense catfish populations. The process involves creating a mixture that will produce carbon dioxide (CO2) gas, which, when released underwater, forms bubbles that can be harmful to the catfish.

CO2 is a product of respiration in animals, including fish, and high levels of this gas can be toxic to them. In the case of catfish, the increased levels of CO2 in their underwater environment signal that something is amiss, prompting them to swim upwards and away from the source. This behavior is a survival mechanism, as remaining in an environment with high CO2 levels could lead to cardiac failure and death.

The toxicity of CO2 to catfish is influenced by various factors, including the developmental stage of the fish. For example, cleavage and juvenile stages of certain marine bony fishes are more susceptible to CO2 than the preflexion and flexion stages. Additionally, the duration of exposure to high CO2 levels plays a role, with longer exposures increasing the risk of adverse effects.

It is important to note that while this method can be effective in causing catfish to leave their holes, it may not always be practical or feasible. The success of this technique depends on several factors, including the size of the catfish population in the area and the accessibility of their holes. Additionally, the use of mentos and coke may be considered a waste of resources in some regions, especially where these items are expensive or hard to come by.

In conclusion, the creation of a CO2-rich environment through the use of mentos and coke is a clever strategy to encourage catfish to leave their holes. However, it is important to consider the potential drawbacks and limitations of this method before employing it as a fishing technique.

The egg clogs the hole, stopping fresh water from filtering through

The viral video that sparked curiosity about the unusual fishing method of pouring eggs into a catfish hole has been revealed to be staged. While it may not be a practical approach for catching catfish, understanding the reasoning behind the use of eggs in the video can provide some interesting insights.

One of the comments on the video suggested that the egg played a crucial role in luring the catfish to the entrance of the hole. By clogging the hole, the egg prevented fresh water from filtering through, creating an unfavourable environment for the fish. This is supported by the fact that catfish are known to surface for air when there isn't enough oxygen in the water.

The egg essentially acted as a barrier, blocking the entry of fresh water and disrupting the natural flow within the catfish's habitat. This disruption may have been intended to create an uncomfortable or unhealthy environment for the catfish, encouraging them to seek alternative sources of oxygen and potentially making them more susceptible to the bait.

It's important to note that this method may not be effective in real-world scenarios, as catfish are not typically found in small water bodies, and the success of this technique has not been verified beyond the staged video. However, the creative use of eggs in the video sparked curiosity and led to interesting discussions about catfish behaviour and fishing techniques.

While the egg played a role in attracting the catfish, it is worth mentioning that the subsequent steps involving Mentos and Coca-Cola were intended to create an CO2-rich environment. This combination of Mentos and soda is known to produce carbon dioxide bubbles, which can potentially trap and suffocate the fish.

The carbon dioxide bubbles suffocate the catfish

Catfish can be difficult to catch, as they often live in holes or crevices in the ground underwater. One method that has been used to try and catch them is to pour beer into their holes. This method is thought to work because of the carbon dioxide that is present in carbonated drinks like beer.

Carbon dioxide, also known as CO2, is a gas that is found in water in dissolved form. It is important for the health of aquatic plants, which depend on it for life and growth. However, when carbon dioxide levels in water become too high, it can be dangerous for fish. This is because, in high concentrations, carbon dioxide can dissolve in water and cause the water to become saturated with the gas. As carbon dioxide is odourless and colourless, it is difficult to detect. This means that fish may not realise they are swimming into dangerous conditions.

When carbon dioxide levels are high, it becomes harder for fish to get the oxygen they need from the water. This is because carbon dioxide competes with oxygen for dissolution in water. As carbon dioxide can dissolve in water 200 times more easily than oxygen, it quickly replaces oxygen in the water. This means that fish can suffocate and die due to a lack of oxygen.

Therefore, when beer is poured into a catfish hole, it releases carbon dioxide into the water. This creates an environment rich in CO2, which makes it difficult for the catfish to get oxygen from the water. The carbon dioxide bubbles that form in the water can also directly suffocate the catfish, as they become trapped within the bubbles. As a result, the catfish are forced to leave their hole in search of healthier conditions, making them easier to catch.
