De-Embiggenifying Potion

You are carrying one.
When poured on the floor, it releases a very pleasant scent (a strange mixture of cherry tart, custard, pineapple, roast turkey, toffee, and hot buttered toast) and a cloud causing people to feel most curious, like they're shutting up like a telescope or some such.
List price: ₡1000.
Made from an Essence of Purple, five Helium and 11 Tiny Bubbles using a Cauldron.
