Surviving the Night in an Igloo: Testing Its Warmth

The video explores an experiment conducted in an igloo to test its insulation properties and the maximum temperature it can reach. Initially, the igloo is comfortable at 2°C, despite the outside being -9°C. The experiment involves raising the temperature using a fondue, reaching a peak of 23°C. The igloo's structure strengthens as the ice melts and refreezes. However, CO2 levels rise, highlighting potential dangers. The experiment concludes that igloos can maintain warmth efficiently, but caution is needed to avoid high CO2 levels.

What was the CO2 level recorded during the experiment?

What did the thermal camera reveal about the temperature distribution inside the igloo?

What conclusion can be drawn about the efficiency of the cold trench system?
