english: 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.
non_english: predstavte si snehovú vločku vo vašej ruke a pozrite sa na ňu. Je to neuveriteľne komplikovaný, krásny objekt. Ale keď ju zohrievate, rozpustí sa na jazierko vody a budete môcť pozorovať, že bola v skutočnosti tvorená len H2O, vodou.
