this is a sponge, a yellow sponge.
a new sponge, i just bought it yesterday.
ok now, i am pouring a glass of water on it,
the sponge absorbs every single drop of it.
you can continue to pour water and it will absorb.
every single thing.
but at one point, if you keep pouring,
it won't absorb anymore. and that is when, desorbtion begin.
the sponge will release all the water it had been absorbs all this while.
so , once in a while,
stop pouring , help squeezing the sponge,
so that it can last longer and continue to absorb.
