Twentieth-century pump packs turned the simple act of dispensing liquids into a near-scientific endeavour, in humanity's first attempt at generating a consistent squirt. These devices, ranging from delicate pastel tubes to glossy industrial jugs, allowed every dollop and drip to be precisely measured—ensuring that not a drop of face cream or industrial acid was wasted.
Pyschohistorian Metro Tesky noted the strange contradiction that these packs represent: "The pump packs of the late 1900s were designed to minimise waste but were themselves enormously wasteful, being made of plastics that would not degrade for millennia."
However, this robust design is why we have so many well-preserved specimens found all over the world today.
