Pop a couple of bricks in a carrier bag, leave it by the front door, when you go out take the bag and just 'forget' it on the bus etc, in a couple of months all your bricks are gone and the local neighbourhood has an interesting mystery to chat about.

Reply to Damp walls, advice needed by mattheweightyfour
The wall is getting regularly soaked or water is condensing there.
Check the outside when it's raining to see if water runs across or splashes near that bit of the wall (doesn't have to be exact), and get a humidity sensor, if the room is humid, buy a ~£100 dehumidifier, not one of the tiny protable ones, a suitcase sized unit. It will take a few days running non stop to dry out the room, pulling tens of litres of water out.
The dehumidifier will make the heating more efficient, speed up drying clothes and stop mold as well.
Took about a fortnight to dry out our flat when we moved in and that was all from long term condensation.

Reply to comment by spectacular_coitus in New approach to ‘cosmic magnet’ manufacturing could reduce reliance on rare earths in low-carbon technologies by FUZxxl
The material is roughly 65%* magnetic strength of Neodymium, it is found in meteorites that had just the right composition and spent millions of years cooling down, now we can simply cast it. It will likely replace rare earths for a lot of applications.
* article says theoretical max of 335 kJ/m^3 for Tetrataenite vs 512 kJ/m^3 for Neodymium
/edit, not an expert, just was curious how it compared and went looking, your comment seemed best place to dump what I found.
