Demonstrating Chemistry - Spectacular Experiments: Dry Ice - The Magnesium Sandwich

The video tutorial demonstrates the magnesium CO2 sandwich experiment, where CO2 acts as an oxygen source, promoting fire. It covers preparing CO2 blocks, drilling pilot holes, and adding magnesium turnings. Safety measures are emphasized, including using a fire blanket and CO2 cylinder. The experiment shows magnesium reducing CO2, resulting in a bright reaction and forming carbon and magnesium compounds. The tutorial concludes with a discussion of the results.

Explain the significance of the magnesium's brightness during the reaction.

What is observed after the magnesium has reacted with the carbon dioxide?
