Paper. Books. Curious hands.
Rainy outside? Your next adventure can still begin. Use everyday materials to come up with your own solutions, test them and discover why something works, or why it needs another try.
- Make something of your own with everyday materials, without a special experiment kit.
- A first attempt does not work? Changing, retesting and rethinking are part of the adventure.
- Fits an afternoon at home: you choose when to begin.

A ball drawn on paper cannot jump. Can your thumb change that?
A little guidance. Your own discovery.
One mission. Three levels of discovery.
See how the challenge changes with age, using this example: The Paper Bridge Rescue.
A glimpse of age-specific challenges, rather than the complete mission.
- Place one counter with your adult. Point to the bend and act out a wobbly bridge with your hands.
- Your adult helps fold. You test one counter on each design and point to the steadiest bridge.
- Predict the first bend and draw where it happened. Keep the books at the marked positions.
- Make a simple table for flat, U-shaped and accordion designs. Compare their loads using the same counters.
- Write down the gap, paper type and first load position. These are conditions you will keep similar.
- Compare three shapes and identify a possible unfair difference, such as damaged paper or unequal support overlap.
What you will need
- Three similar sheets of paper
- Two closed books of equal height
- Six large, lightweight counters or clean bottle caps
- A pencil
The missions are designed for children with a grown-up. The app shows materials and guidance before you begin.
