How do you make an earthquake simulator?

To make an earthquake simulator, you will need a few materials, such as a wooden box, a motor, a platform, a weight, and a power source. First, attach the motor to the platform and the weight to the motor. Then, place the platform inside the wooden box and secure it with screws. Finally, connect the power source to the motor and turn it on. The motor will cause the platform to vibrate, simulating an earthquake.
