A Leap of Faith - OECD

This activity is the perfect way to show that gas takes up space, as it is responsible for blowing up the balloon. Gas Law / IMF Common Gas Law Experiments Collapsing Balloon (Charles’ Law) Description: A filled balloon shrinks when immersed in liquid nitrogen. Materials: Liquid Nitrogen Balloons Dewar Tongs Insulated Gloves Flashlight Procedure: Carefully fill dewar with N2 ( l). Add balloons to the dewar (suitcase analogy often used). The balloon gets inflated quickly.

One of the first balloon experiments most kids try is rubbing a balloon on their hair to make it stand on end. The next step is to hold the balloon over a compact fluorescent lightbulb (CFL) to see it glow from the static electricity.

What we learn 2020-05-06 Baking soda and vinegar balloon experiment explanation: The reason that we are able to inflate a ballon in this experiment is thanks to the magical reaction of the baking soda and vinegar. As the baking soda and vinegar interact they release a gas (carbon dioxide) and increase the air pressure in the bottle.

This will let you to observe how gases expand and contract as the The baking soda will quickly react with the vinegar in the flask, creating carbon dioxide gas as one of its products, causing the balloon to quickly inflate. After the reaction is complete the balloon will remain inflate. You can pop the balloon with a tack if you wish to confirm with the students that the balloon was filled with gas. When the two ingredients mix together the balloon baking soda experiment gets it’s lift! That lift is the gas produced from the two ingredients is carbon dioxide or CO2. As the gas tries to leave the plastic container, it goes up into the balloon because of the tight seal you have created. This experiment demonstrates how states of matter can change – mixing a solid with a liquid to create gas! The science, behind this balloon baking soda experiment, is the chemical reaction between the base – baking soda – and the acid – vinegar.
