Description

Build your own Fire Extinguisher HOW IT WORKS Explanation: The baking soda and vinegar react to make carbon dioxide, a gas that is heavier than oxygen. As it "pours" out of the bottle. it pushes the lighter oxygen away from the candle. The fire. now deprived of oxygen, can no longer bum. A typical fire extinguisher works by spraying foam that prevents the fire from getting oxygen. Commercial versions store a liquid under pressure that reacts with oxygen to produce the foam. A fire extinguisher typically deprive a fire of oxygen. If you encounter a fire at home, on a stovetop, for example, you can smother the fire by putting a lid over your pan or pot. In some cases, you can toss a non• flammable chemical on the fire to reduce the combustion reaction. Good choices include table salt (sodium chloride) or baking soda (sodium bicarbonate). When baking soda is heated, carbon dioxide gas is given off. suffocating the fire. In this project, you'll cause a chemical reaction to produce carbon dioxide gas. The carbon dioxide sinks in the air. displacing it and removing oxygen from the fire. One of the critical skills required for any scientist is the ability to consistently design and carry out successful experiments. There are of course many variables that can cause an experiment to fail, but there are some basic steps that, if taken routinely, can increase your chances of success every time. Safety Guidelines : Fire, Chemical handling, Eye Safety, Clothing protection & Glassware ... Always conduct your experiments with adult supervision. ... Never smell or taste any chemicals unless instructed to do so by your teacher and the. When working with chemicals, chemical safety goggles, gloves, and a lab coat should be the first pieces of equipment on your list . This product is designed for a demonstration purpose and single use. Apply your creativity while assembling. Assembly manual is provided with the kit. The project is for demonstration and informational purposes only. All of Junior Scientist products are unique and handmade. We work by designs and Endeavour to create like products. However the very nature of being individually designed by hand gives raw finishing of the projects since it should look that students have created on its own.
