Fermentation of Yeast & Sugar - The Sci Guys: Science at Home
Summary
TLDRIn this episode of S guys, hosts Ryan and Teresa explore fermentation with sugar and yeast, demonstrating how different amounts of sugar affect gas production. They use bottles, yeast, sugar, and balloons to show that yeast metabolizes sugar into carbon dioxide and ethanol, causing balloons to inflate. The more sugar, the greater the gas production and balloon expansion. The video concludes with a call to action for viewers to support their channel and engage with them on social media.
Takeaways
- đŸ Today's experiment on S side is about fermenting yeast with sugar to produce gas.
- đ The experiment is a viewer-requested episode focusing on the chemical breakdown of substances by microorganisms.
- đ§Ș The necessary equipment includes bottles, sugar, yeast, balloons, a funnel, measuring utensils, and warm water.
- 𧀠Safety measures like gloves, goggles, and an apron are recommended even though there are no hazardous materials involved.
- đ The process begins by adding yeast and varying amounts of sugar to different bottles, followed by warm water.
- đ Balloons are placed on the bottles to capture the gas produced during fermentation.
- â± Over an hour or two, the balloons will grow in size as a result of the gas produced.
- đ The balloon over the bottle with the most sugar will expand the most due to increased carbon dioxide production.
- đŹ Yeast metabolizes sugar, producing carbon dioxide and ethanol as waste, which causes the balloon to inflate.
- âïž The experiment demonstrates that more sugar results in more yeast food, leading to more gas and a larger balloon.
- đą The video concludes with a call to action for viewers to support the channel, subscribe for future episodes, and engage on social media.
Q & A
What is the main topic of the video?
-The main topic of the video is fermentation with sugar and yeast, focusing on the production of gas through the process.
What are the potential hazards involved in the experiment?
-There are no hazardous materials involved in the experiment, but the video recommends using gloves, goggles, and an apron or lab coat to protect from spills and splashes.
What equipment and ingredients are needed for the experiment?
-The equipment and ingredients needed include multiple bottles (glass or plastic), sugar, yeast, balloons, a funnel, measuring utensils, and warm water.
How much yeast is used in the experiment?
-The experiment uses one package or 2 and 1/4 teaspoons of yeast per bottle.
How does the amount of sugar added to the bottles vary?
-The amount of sugar varies from no sugar in the first bottle, 1 teaspoon in the second, 2 teaspoons in the third, and 3 teaspoons in the fourth.
What is the purpose of the balloons in the experiment?
-The balloons are used to collect and visually demonstrate the carbon dioxide gas produced by the yeast as it ferments the sugar.
What happens to the balloons over the course of the experiment?
-Over the course of the experiment, the balloons gradually grow in size as they fill with carbon dioxide gas produced by the yeast.
Why does the balloon grow larger with more sugar in the bottle?
-The balloon grows larger with more sugar because there is more food for the yeast to consume, resulting in more carbon dioxide gas production and increased pressure inside the bottle and balloon.
What is the role of yeast in the fermentation process?
-Yeast plays a crucial role in fermentation by consuming sugars and starches, breaking them down to produce energy, and releasing carbon dioxide gas and ethanol as waste products.
What is the chemical reaction equation for the fermentation process described in the video?
-The chemical reaction equation is not explicitly provided in the transcript, but it generally involves the breakdown of sucrose (sugar) by yeast to produce ethanol and carbon dioxide.
How can viewers support the creators of the video?
-Viewers can support the creators by becoming a patron on Patreon, as mentioned in the video.
What should viewers do if they have questions related to the experiment?
-Viewers can ask questions in the comments section of the video or message the creators on Facebook, and they will try to help as best as possible.
