The device consists of two vessels which are filled with lime water. The air breathe in and out is separated in vessels respectively. The vessels are fixed in a tripod shipping with the device. Since the speeds of liquid dimming vary, one has to conclude that the amount of CO2 in breathed out air is more than the amount of CO2 in breathed in air.
