Two glass vessels are connected by funnel with paper or cotton filter attached on top. The process is taking advantage of the basic physical law of gas expansivity. Hot water is poured into the bottom chamber. Once boiling, the vapour starts to expand vertically into the upper vessel. Here it mixes with ground coffee and undergoes extraction. After approx. 70 seconds, the heat source is switched off and coffee can be sucked back to the bottom chamber. The result is a clean and delicate cup together with many astonished faces of the spectators.
