a muggleborn student coming to hogwarts with a thermos flask and filling it with tea in the morning so it stays hot all day and their pureblood friends are like “whoa what spell did you use for that” and they’re like “?????? it’s just a thermos???” and all the pureblood students start pointing their wands at cups and saying “THERMOS”
THERMOS
plot twist: it works, mugs suddenly start keeping tea at the perfect temperature for the caster all day. students in muggle studies start experimenting with other muggle jargon and a new generation of magic spells are born, propelling the stagnated wizard community into the technological age
