"This separation from his spellbooks had been a real problem for Harry, because his teachers at Hogwarts had given him a lot of holiday work. One of the essays, a particularly nasty one about shrinking potions, was for Harry’s least favourite teacher, Professor Snape, who would be delighted to have an excuse to give Harry detention for a month."
—Harry Potter muses on problems in doing his summer revision[src]

This essay on shrinking potions was assigned by Professor Severus Snape to his upcoming third year students over the summer holidays of 1993. It covered potions capable of shrinking the drinker, including presumably the Shrinking Solution that would be brewed that year. The essay was difficult as compared to those assigned by other teachers that year; Harry Potter felt it was "particularly nasty".[1]
