Today i learnt something rather amusing to me.

Silica Gel


plus water equals


mouse:"dammmmmnnn" (if you know what i mean..)
oh and this is reversible. heat the pink and will get back blue! whats the reaction involved? the silica gel is so hard where did the water go? ther was no increase in size. and if you pour in water too fast it will break like a glass ball. oh and its exothermic!! ermm "reaction" if there is any, which i guess not! obviously.

humm i have no answers though. but i think i will ask around.
Peace !
