Town Gas Mattress Cover Trap

A worn mattress cover functions as an improvised explosive device, filled with town gas by the Doctor and ignited via a lit fuse of paper. The makeshift bomb shows signs of hasty construction—rough stitching along closed seams hides the volatile contents while the fabric bears the grimy smears of grease and ash from the Doctor’s improvised work. The object’s thin, worn material strains under the weight of the trapped gas, its fragility stark against its deadly purpose.

Before: Standard linen in the kitchen, unremarkable save for wear.

After: Ruptured violently by internal explosion, fabric scorched and fluttering with residual flame.

Before: Worn, grease-stained cover with rough seams freshly stitched to seal town gas inside

After: Torn and blackened by flame, fibers smoldering, contents violently expelled
