Dry Ice and Magnesium

The video explores how carbon dioxide, typically used to extinguish flames, can instead fuel combustion under certain conditions. An experiment is conducted using magnesium and dry ice to demonstrate this phenomenon. The magnesium burns in a redox reaction, stripping oxygen from carbon dioxide, resulting in magnesium oxide and elemental carbon. The video highlights the importance of understanding chemical reactions and the limitations of carbon dioxide extinguishers on metal fires.
