Tumble Glass

In The Kingkiller Chronicle, the Tumble Glass emerges in The Wise Man's Fear as a cleverly designed whiskey glass with a rounded bottom that rolls when placed upright, symbolizing Kvothe's penchant for unconventional indulgences amid his tumultuous journey. Its defining moment arrives during an earnest toast, where it is deliberately inverted to remain stable, highlighting themes of adaptability and defiance against conventional stability. Though appearing only in the second book thus far, the Tumble Glass encapsulates the series' blend of whimsy and profundity, potentially foreshadowing deeper alchemical or narrative inversions in later volumes.
