Avui hem repescat un experiment que ja vam fer l’any passat: la massa no newtoniana.\u00a0 \u00c9s un experiment molt senzill de fer que nom\u00e9s requereix de dos ingredients: Maizena i aigua.\u00a0 Tots coneixem l\u00edquids, com la llet o l’aigua, 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…l’anomenada massa no newtoniana.<\/p>\n

Hem comen\u00e7at l’experiment barrejant un paquet de Maizena amb un got i mig d’aigua 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

Aqu\u00ed us deixem algunes fotografies i us animem a que feu aquest experiment a casa<\/p>\n
