Bathsheba...... Large black plastic rubble sack, shaken wide open. Loosen the top of the dust box, but definitely not opened fully. Put dust box into the rubble sack, holding it through the sack itself, with one hand. With the other hand, snatch off the lid of dust box, shake dust box violently to shake contents to the bottom of the sack and whip out both the box and the lid as quick as you can. Grab the sack around the middle, knot it and throw it in the bin as quick as possible. Don't use the dustbin again until its been emptied. Just in case.shudder
