Sab\u00edeu que, a causa de la tensi\u00f3 superficial, els l\u00edquids presenten una tend\u00e8ncia a reduir la forma exterior que mostren. D’aquesta manera, si el volum de l\u00edquid es deixa lliure a l’aire i entra en contacte amb un altre l\u00edquid de la mateixa densitat, es situar\u00e0 de manera que tindr\u00e0 la menor superf\u00edcie possible compatible amb el seu volum.<\/p>\n

Aix\u00ed, ja ho veieu, darrera de les sorprenents bombolles de sab\u00f3, hi ha matem\u00e0tica! Incertesa, aventura i efemeritat de cossos geom\u00e8trics tessel.lant l’espai, en suspensi\u00f3. I s\u00ed, per descomptat, a m\u00e9s a m\u00e9s de ci\u00e8ncia, diversi\u00f3!<\/em><\/p>\n
