KARTONIA — He Built It Himself: 120 Cardboard Projects, Ages 5-12, Nothing to Buy

120 engineering projects he builds out of cardboard.

Cranes with working pulleys, vehicles with bottle-cap wheels, machines with parts that actually move — all built from cereal boxes and whatever's already in your recycling bin.

• Sorted into three real age bands — 5-7, 8-10, 10-12. Not "for kids".
• Instructions are drawn, not written. He reads pictures, not paragraphs, so he keeps going without you.
• Cardboard, scissors, glue. No electronics, no batteries, nothing to buy and nothing to wait for.
• Five-minute steps that each end in something he can pick up and show you.
