Why Paper Planes Fly Far

A folded piece of paper can glide across the whole classroom. How does it stay up in the air?

In this Spark you'll discover the secret forces that keep planes flying — and how to fold one that flies really far. Tap Next to begin! 👉

Four invisible pushes

Every flying thing is pushed by four forces. Tap each glowing arrow to find out what it does!

Wings catch the air

Flat, even wings catch the air smoothly and create lift — the push that keeps your plane gliding instead of dropping.

🛫

Big flat wings
More air to push on = more lift = longer glide.

🪶

Even & straight
If both wings match, the plane flies straight, not in circles.

Try it next: see how the throw angle changes everything! 👉

Make a pointy nose

Air pushes back on the plane — that's drag. A sharp, streamlined nose slices through the air. A crumpled, wide nose gets stuck. Tap the button to morph the plane!

Right now the nose is blunt — lots of drag!

Find the perfect angle

How you throw matters! Too flat and it dives; too steep and it stalls. Drag the slider to aim, then press Throw! Can you reach the far wall? 🎯

Angle: 25°

Pick an angle and throw.

Balance the plane

A plane must not be too tail-heavy or it flips and tumbles. A tiny bit of weight near the nose keeps it steady. Where should a small paperclip go?

Tap your answer.

Spot the better plane

You're ready to design! Tap the choice in each pair that flies farther.

1. Wings:

2. Nose:

Make both choices above.

🏅✈️

You did it!

Now you know the secrets of a far-flying paper plane:

Lift Flat, even wings push the plane up.
Drag A sharp, pointy nose slips through the air.
Thrust A firm throw at about 30°–40° goes farthest.
Balance A little weight near the nose keeps it steady.

🛠️ Try it for real: fold a plane, throw it, then change one thing — the angle, the nose, or add a paperclip — and see what flies farthest!

Great work, flight engineer. Keep exploring! 🚀
