Great choice, Junior Scientist! Today we're doing the "Paper Bridge Strength Test" experiment. Let me explain what we'll discover together. Folding paper into a zig-zag makes it stiffer by adding height and triangles — shapes engineers use in real bridges. More structure means the bridge spreads out the weight and holds more!
Place two books about 15 cm apart as bridge supports.
