Hold Fire In The Palm Of Your Hand! | Science with Hazel
Summary
TLDRIn 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
- π§ͺ Today's experiment involves making methane bubbles.
- π§ The container has water mixed with a large amount of fairy liquid (washing up liquid).
- π¬ The gas tap is used to pump methane into the mixture.
- π Wet hands with water and washing up liquid before attempting to scoop up the bubbles.
- π Remove all jewelry from hands to avoid any risk during the experiment.
- π Scooping up the bubbles is done carefully to prevent any mishap.
- β« The methane bubbles rise due to being lighter than air.
- π₯ The complete combustion of methane produces water and CO2, a reaction to remember for IGCSE.
- π¬ The water in the mixture also serves as a protective layer against the heat from combustion.
- π 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.
