The sand rammer machine can be used to measure compactability of prepared sand by filling the specimen tube with prepared sand so that it is level with the top of the tube.

Compactability in percentage is then calculated from the resultant height of the sand inside the specimen tube.

Then he placed the specimen tube beside the communicator.

That evening, as they were readying the day's tube for Castor, Liu let out a whoop, holding up a glowing specimen tube for the others to see.
