Rượu và các địa điểm trao đổi nước??
Cover up a glass of water with a thin pasteboard, turn it over and put it on the glass of red wine. Brims of both glasses have to be completely covered. Pull out the carton to make a tiny gap between the glasses. Vine which is less dense than water immediately starts to lift up to the upper glass, while water slips to the lower glass. In a while the liquids will change sites, all wine will be in the upper glass and water in the lower glass. The narrow gap doesn’t allow fluid mixing. This is physics experiment for science project. http Kozarec z vodo pokrij s tankim kartonom, ga obrni ter postavi na kozarec z vinom. Robova kozarcev naj se popolnoma prekrivata. Nato izvleci karton le toliko, da bo med kozarcema nastala ozka odprtina. Vino, z manjšo gostoto kot voda, se bo takoj začelo v tankem stebru vzdigovati v zgornji kozarec, medtem ko se bo voda spuščala v spodnjega. Čez nekaj časa bosta tekočini zamenjali svoji mesti, vino bo v zgornjem, voda pa v spodnjem kozarcu. Ozka odprtina ne dopušča mešanja tekočin.
