So how does the siphon coffee machine work? science!

There are two rooms, the first one is full of water. By heating the bottom cavity, the steam pressure forces the water to rise to the upper cavity. Here, it is mixed with coffee grounds.

The water, now mixed with the ground, is pulled back to the lower chamber (due to gravity and pressure drop, the "vacuum" effect), passing through the filter at the bottom of the upper chamber, which in turn is filled with brewed coffee.
