Antidote Served Cold

Players have a container with water but the liquid is at room temperature. There is a hint that they have to pour it into a bowl. The bowl is fixed to the table and the water (let's call it a potion/antidote) has to be cold. Prepare a way for cooling the water down, preferably an ice cube dispenser. There is a Temperature sensor hidden at the bottom of the bowl. After players pour cold water into the bowl, the Temperature sensor triggers, and the puzzle is won. Players hear the pre-recorded voice of a cured man from a painting and after the recording ends, the painting reveals a hidden compartment behind it. Electronics needed: 🌡 Temperature sensor, 🧩 Universal puzzle controller, 🖼 Painting Mystery output set
