Carbon Dioxide Race - Lap 2
This experiment is a variation on the first carbon dioxide race, where this time we watch the carbon dioxide extinguish the flames from the bottom of the tank to the top as a thicker layer builds up and spills over the beaker. Why does a layer build up from the bottom? Ask your students - they may remember from an earlier experiment
