This Pop Light is exactly what it is, a light turned on by pushing it down and essentially "popping" it. The bulbous middle section is thin plaster printed with a pattern on the inside. This way when the light comes on you are confronted with a surprise pattern and color that was not there before. The top nodes are a soft plastic which is fun to touch and are slightly transparent so they glow. The whole light is charged via an electrical outlet and can stay lit up for 12 hours after being charged.
