Shrinking Solution, also known as a Shrinking Potion, is a potion that causes the drinker to shrink to a smaller form. It is bright green when brewed correctly and, if prepared incorrectly, it can apparently be poisonous.
Sometime throughout wizarding history, wizard Samuel Plunkett, who was persecuted by a Muggle village, poured Shrinking Solution down the village well and terrorised the shrunken villagers by chasing them around in hobnail boots.
In the 1500s, accomplished potioneer Zygmunt Budge developed his own version of this potion, which, in his words was "the best you will find". According to Budge, part of the potency of his variation came from stirring the potion after adding the Shrivelfigs, an unorthodox step. It proved so powerful that, when he accidentally split a small ammount on the grass outside his house, it caused an entire flock of sheep to shrink to lambs the size of woolly mice (Budge went on to use the shrunken lambs as ear-warmers in the chilly winters at Hermetray). Budge also sent the potion to the two brothers of Tertius. Both of them shrank to the size of beetle, and, so the story goes, spent several days hiding under a cupboard while their cat tried to scoop them out and eat them.
Professor Severus Snape assigned his then-second year students a "particularly nasty" essay on shrinking potions during the summer holidays, and when they returned that fall, the first potion he had them brew was this one. When Draco Malfoy, who had injured his arm being attacked by Buckbeak the Hippogriff, returned to class, Snape had Harry Potter and Ron Weasley brew his potion for him. In the same lesson, Neville Longbottom added too much leech juice and rat spleens to his potion, and Professor Snape threatened to poison Neville Longbottom's pet toad, Trevor, with the botched potion at the end of class. Luckily, however, Hermione Granger helped Neville fix it and when it came time for Snape to test the potion, Trevor turned into a tadpole.
