This sounds fake.
Britain’s WWII saboteurs stuffed dead rats with plastic explosive to blow up boilers.
The first shipment was seized, yet the Germans staged exhibits and went looking for more anyway.
The part that checks out ↘
It really happened.
Britain’s Special Operations Executive prepared rat skins packed with explosive, with a small fuse inside. The plan was to leave them among coal, so a stoker might throw one into a furnace and the blast could rupture a boiler. The first batch was seized and never used, but the capture prompted German exhibits and searches for more—creating alarm and nuisance from a device that mostly existed as a threat.
It recasts sabotage as psychology as much as physics: one captured gadget forced an enemy to look for ghosts. A threat can work even when it never goes off.
No folklore. Actual sources.
