Sand kneaded with saltwater
and scooped with a bucket
keeps its shape when overturned.
It will crumble if it dries,
and will fall once again into sand,
knocked loose of all tension.
The inverse of sand is snow.
Snow will also respond well
to condensing, to being packed
in a gloved grip to temporary solidity.
Sand, snow--kick it, throw it,
build with it. Use it to destroy
or assemble. It will regenerate,
smithereens of lost water or ground.
