Runner Up: Slime Hand (Yutaro Sato, Kento Imai and Kenri Kodaka)
We’ve seen various interpretations of this illusion before, where participants believe their hand is being maliciously manipulated (think fire, pin pricks, hammer blows) when in reality it’s safely hidden out of sight behind a divider. In this version a blob of green slime next to a mirror makes participants believe their real hand, safely hidden behind the mirror, is being stretched and manipulated in impossible ways.
