How to Make a Cloud in Your Mouth

Key Concepts:

• Makeulus Ridiculous Cloud: A cloud created inside the mouth using specific tongue and pressure techniques.
• Water Droplets: Tiny particles of water formed in the mouth during the tongue-clicking process.
• Evaporation: The process by which water droplets turn into water vapor.
• Humid Air: Air containing a high amount of water vapor.
• Pressurization: Increasing the pressure inside the mouth by holding it closed and attempting to blow out.
• Ideal Gas Law: A principle stating that when pressure increases, temperature also increases (at constant volume).
• Water Vapor (H2O gas): Gaseous form of water.
• Condensation: The process by which water vapor turns back into liquid water droplets.

Creating the Makeulus Ridiculous Cloud

The video demonstrates a method for creating a small cloud that billows out of the mouth, playfully termed a "Makeulus Ridiculous" cloud. The process involves two key steps:

1. Tongue Clicking: The first step involves clicking the tongue on the roof of the mouth with the mouth closed and full of air for approximately 30 seconds. This action serves to create tiny water droplets within the mouth. These droplets evaporate more easily, leading to the formation of warm, humid air.

2. Pressurization and Release: The second step involves pressurizing the mouth. This is achieved by holding the mouth closed and attempting to blow out, thereby increasing the pressure inside. According to the ideal gas law, this pressurization also causes the temperature of the air inside the mouth to rise. Warmer air can hold more moisture in the form of water vapor (H2O gas). Finally, the pressure is released, allowing the air to escape slowly.

The Physics Behind the Cloud

The formation of the cloud is explained through basic physics principles:

• Initial Water Droplet Formation: Clicking the tongue creates tiny water droplets, increasing the surface area for evaporation.
• Humid Air Creation: The evaporation of these droplets leads to the formation of warm, humid air inside the mouth.
• Temperature Increase via Pressurization: Pressurizing the mouth increases the temperature of the air, allowing it to hold more water vapor. The ideal gas law is invoked to explain this relationship.
• Condensation upon Release: When the pressurized air is released, the pressure drops, causing the temperature to decrease. This temperature drop, combined with the cooler outside air, causes the water vapor to condense into tiny water droplets, forming the visible cloud. The humid air cools, and it can no longer hold all of the water vapor, so some of it condenses out into itty bitty water droplets.

Conclusion

The "Makeulus Ridiculous" cloud is a demonstration of basic physics principles, specifically the ideal gas law and the processes of evaporation and condensation. By manipulating pressure and temperature within the mouth, it's possible to create a visible cloud of water droplets.
