Why can't water go through sand?

Water can go through sand because sand is porous which means it does let water through :) hoped it helped if it did don't forget to say thanks !

Sand is porous . . . so water can go through it.  I dare you try a little experiment.  Go to the beach with a Styrofoam cup, fill it up with sand (not the stuff all muddied up with twigs and algae, but the good stuff just a few feet in the water), then fill the cup up with water, then poke a hole in the bottom . . . out will come the water and not much of the sand . . . why? . . . because water can go through sand

Fine out your self ponk
