imagine a snowflake in your hand, and you look at it, and it's an incredibly complicated, beautiful object. But as you heat it up, it'll melt into a pool of water, and you would be able to see that, actually, it was just made of H20, water.
zamislite snježnu pahuljicu na dlanu, gledate ju i nevjerojatno je složena, prekrasna pojava. Ali kako ju grijete, topi se u lokvu vode, i na kraju vidite da je, zapravo, sazdana od vode, H2O.
