Sukladno tomu porastom <a href="/wiki/Nadmorska_visina" title="Nadmorska visina">nadmorske visine</a>, smanjuje se stupac atmosfere poviše, i atmosferski tlak sukladno tome opada.

Zatim ju je začepio prstom, okrenuo i stavio okomito u posudu sa živom. Živa nije ostala do vrha u cijevi, ali nije ni sva iscurila. Prostor iznad žive je prazan prostor, a zove se Torricellijev <a href="/wiki/Vakuum" title="Vakuum">vakuum</a>.
