Emily's Science Lab: DIY Fire Extinguisher Experiment explores the science behind fire extinguishers using simple household materials. Hosted by MIT engineer Emily Calandrelli, the video demonstrates how the reaction between baking soda and vinegar creates carbon dioxide, a key component in many fire extinguishers. This dense gas displaces oxygen, extinguishing flames effectively. The video introduces basic chemistry concepts such as acid-base reactions, emphasizing the practical application of chemistry in safety devices. As Emily guides through this fun and educational experiment, viewers learn about the properties of gases and their role in fire suppression. Part of Emily's Wonder Lab series, this content encourages exploration and curiosity about science topics. The video is an excellent resource for understanding basic chemical reactions, making it relevant and informative for science learners engaged in early chemistry education.
