This is the Beeping Earth. It is a hollowed out foam ball with a CPX being housed inside of the ball. When functioning, the Beeping Earth will be quiet all the time. Until light travels through a hole at the top of the Earth. The best type of light to use a flashlight. When the CPX senses a high amount of light, it will beep and light up red. Due to the ball being made of foam, the red light shines a little through the foam.

It works by using a CPX that is sensing light. Low light and normal room lit areas are not enough to cause the CPX to respond. It is set up so that the CPX will only be disturbed by a bright light. The light I have used to test the CPX is the flashlight from my smartphone, because it is brighter than the normal lights in a room
