Guess the Car
★Exhibit Content: Probability and Logical Thinking Science Interactive Game ★Interaction: Electromechanical Interaction ★Operation: Visitors press the start button, and the drum rotates randomly before stopping; then they select the guessed button and press the confirm key; the system displays the result through conductive glass. If guessed correctly, a car pattern is shown; if guessed incorrectly, no pattern is shown, providing an intuitive experience of probability changes and decision logic. ★Exhibit Overview: The exhibit mainly consists of a display stand, drum, stepper motor, protective cover, conductive glass, sensors, and control system. It is a recommended exhibit from the PopsciCat Exhibit Store. The drum is mounted on the display stand, with a stepper motor installed inside. The stepper motor drives the drum to rotate via a synchronous belt. The drum is evenly divided into three patterns, one of which is fixed with a car pattern. The protective cover is installed on the display stand, and conductive glass is installed on the triangular cross-section protective cover. Visitors press the start button, the drum rotates and then stops. They select the guessed button, the conductive glass conducts, and it is guessed whether it is a car pattern; if guessed correctly, the pattern with the car appears; if guessed incorrectly, no car pattern is displayed; when the first option is not selected correctly, the probability of the remaining two being selected increases. ★Scientific Principle: Conditional Probability (Monty Hall Problem): At the initial choice, the probability of selecting the car is 1/3; after the host opens a wrong door, the probability of winning by switching choices increases to 2/3, intuitively demonstrating the change in conditional probability. Random Events and Probability: The random rotation of the drum simulates the randomness of events. Visitors can experience the difference between probability stability and randomness through multiple participations.
