Pouring the sand

That's right '"pouring'" the sand -we'll see how it works eh..
the trick was to use microballons like the ones you buy to make the snow on dioramas, then tint it with paints, and then pour the stuff on the right places.

Why '"pour'"? well because the stuff is half liquid, it will roll naturally around the various emebeded stuff, from the boat to the little bricks that will be added later!
