Hold Fire In The Palm Of Your Hand! | Science with Hazel

Summary

In this engaging science video, Liam and Emilia demonstrate how to make methane bubbles using water, fairy liquid, and a gas tap. Emilia explains the process, wetting her hands to create a barrier, then scooping the methane. The video humorously highlights the methane's lighter-than-air property and safety measures. It also educates on the complete combustion reaction, essential for IGCSE, showing methane reacting with oxygen to produce carbon dioxide and water.

Takeaways

• 🧪 Today's experiment involves making methane bubbles.
• 💧 The container has water mixed with a large amount of fairy liquid (washing up liquid).
• 🔬 The gas tap is used to pump methane into the mixture.
• 👐 Wet hands with water and washing up liquid before attempting to scoop up the bubbles.
• 💍 Remove all jewelry from hands to avoid any risk during the experiment.
• 🌀 Scooping up the bubbles is done carefully to prevent any mishap.
• ⏫ The methane bubbles rise due to being lighter than air.
• 🔥 The complete combustion of methane produces water and CO2, a reaction to remember for IGCSE.
• 🔬 The water in the mixture also serves as a protective layer against the heat from combustion.
• 🎓 The experiment highlights the importance of understanding chemical reactions and safety measures in a scientific setting.

Q & A

What is the main experiment being conducted in the video?

The main experiment in the video is making methane bubbles using water, fairy liquid (washing up liquid), and a gas tap to pump methane.

Why does Liam wet his hands with water and washing up liquid before the experiment?

Liam wets his hands with water and washing up liquid to create a film that will hold the methane, allowing him to scoop up the bubbles.

Why does Liam remove all the jewelry from his hands before the experiment?

Liam removes jewelry to prevent any potential hazards or reactions with the chemicals used in the experiment.

What is the purpose of using a meter roll with a splint on the end?

The meter roll with a splint is used to ignite the methane bubbles, demonstrating their flammability.

Why does the methane bubble rise up from Liam's hands?

The methane bubble rises because methane is lighter than air, causing it to float upwards.

What is the significance of the water protecting Liam during the experiment?

The water acts as a protective layer, shielding Liam from the direct contact with the methane, which could be hazardous if ignited.

What is the complete combustion reaction that Emilia mentions in the script?

The complete combustion reaction refers to the process where methane reacts with oxygen to produce carbon dioxide and water.

Why is the complete combustion reaction important for the IGCSE curriculum?

The complete combustion reaction is important for the IGCSE curriculum as it is a fundamental concept in chemistry, illustrating the principles of combustion and chemical reactions.

What is the role of the fairy liquid in the experiment?

The fairy liquid acts as a surfactant, helping to reduce the surface tension of the water and allowing the methane bubbles to form more easily.

What is the significance of the laughter in the script?

The laughter signifies the excitement and enjoyment of the participants during the experiment, indicating that it is a fun and engaging science activity.

What is the safety precaution taken when handling the methane bubbles?

The safety precaution includes wetting hands with water and washing up liquid, removing jewelry, and using a meter roll with a splint to ignite the bubbles safely.
