The wonders of technology never cease to amaze us!

This ad released by Japanese infrastructure company Kandenko features a pen containing ink that can conduct electricity.

As the pen traces along line drawings of houses, buildings and infrastructures on paper, the bulbs light up once the ink connects the circuits. Watching the lit-up paper come to life as 3D miniature structures will make you feel like a kid all over again.

According to RocketNews24, the producers of the ad drew inspiration from children’s pop-up books.
