Connect 2 bottles together 1 filled with water. Turn the joined bottles upside down, swirl the water round and round, then watch what happens. Only a small amount of water flows into the lower bottle because of the reduced pressure above. By swirling the upper bottle in circles, water begins to pour again and a vortex is created. Size: D32 x H48mm.
