Avui hem fet massa no Newtoniana.\u00a0 \u00c9s un experiment molt senzill de fer que nom\u00e9s requereix de dos ingredients: Maizena (farina de blat de moro) i aigua.\u00a0 Tots coneixem l\u00edquids, com la llet o l\u2019aigua, que es poden transformar en s\u00f2lids posant-los al congelador.\u00a0 O al rev\u00e9s, s\u00f2lids que es poden transformar en l\u00edquids aplicant-los calor, com la neu.\u00a0 Per\u00f2 heu vist mai un l\u00edquid que es converteixi en un s\u00f2lid nom\u00e9s aplicant-li pressi\u00f3? Doncs aqu\u00ed el teniu\u2026l\u2019anomenada massa no newtoniana.<\/p>\n
Hem comen\u00e7at l\u2019experiment barrejant un paquet de Maizena amb dos gots d\u2019aigua aproximadament.\u00a0 Ha costat una mica (per la resist\u00e8ncia que t\u00e9) per\u00f2 quan ha estat ben barrejat hem fet v\u00e0ries proves: quan toc\u00e0vem suaument la massa, aquesta ens deixava enfonsar els dits per\u00f2 quan ho f\u00e8iem amb for\u00e7a o fent un cop semblava m\u00e9s dura que una pedra.\u00a0 Fins i tot pod\u00edem fer boles com si fos plastilina per\u00f2 quan par\u00e0vem de fer for\u00e7a la massa ens regalimava com si fos iogurt.<\/p>\n
