Learning with Fun- Engineering

 Julia and Max explore amazing inventions from the past and today. Readers build a catapult, a cup telephone, and a magic pen that lifts paper using static electricity.

Each chapter includes a wheel to guess old inventions. Ice caves become the first refrigerators, and beavers inspire clever engineering ideas.

The story travels through time to show how simple tools, beds, windows, wheels, and flying machines changed life. Old ideas turn into new inventions step by step. The final challenge is to design a new invention, with the dream of creating a real time machine.

Great for curious minds who enjoy science, building, and creative thinking.
