The cardboard challenge event was originally inspired by "Caine's Arcade", a video of an arcade a child built from repurposed cardboard from his father's auto parts shop.
The UNIS Cardboard challenge is a chance for children to build, guided by their own imaginations and inclinations, but with support from adults. This year the theme was "Greening the Blue" and was aligned with a major UN project.
The event produced some amazing creation:
- Battery recycling devices
- Solar panels that power their homes, computers, etc
- Electric trucks
- Garbage eating robots
- Recycling boats to clean the ocean
