Congrats on allowing us all to have a NEGATIVE WEIGHT. It's rather simple, put a whole bunch of cauldrons into one cauldron (WHAT IN THE WORLD, aren't they the same size... come on.. really). anyways... reconnect.. take them all out and drop the last one... something to that effect.. my weight was -410 KG.
