What if we built a paper bridge?

Build it. Load it. Redesign it.

The challenge

Can it hold 10 pennies?

For curious kids and calm grown-ups

Less passive watching. More “let’s try that again.”

Clear to start

Materials, a mission, and an easy way into the first experiment.

Open to explore

Every result creates a record to beat or a variable to change.

The What If method

One box. Three ways to go bigger.

Each challenge starts with a real-world question, then hands the next move to the kid holding the materials.

01
Try it
Make the first version.
Read the What If Card, make a prediction, and build with the included materials.
02
Beat it
Turn the result into a record.
Add pennies, measure distance, or count seconds. A clear target makes every redesign matter.
03
Break it
Change one variable. Ask again.
Modify the design, test a theory, and share what changed. The next experiment is yours.
