The goal is simple but the physics are fun: Design a plane or glider that can be launched by a "stomp" on the bottle and travel the furthest linear distance from the starting mark. We are looking for the aircraft that covers the most ground before it comes to a final stop. YOU MAY ALSO BUILD A LAUNCH RAMP (WE RECOMMEND IT!)

Maker Tips for Success:

The Launch Angle: Don't just point it straight ahead! Experiment with the angle of your launcher. Launching at a 45 degree angle is often the "sweet spot" for distance, but if your plane is a great glider, a slightly flatter angle might help it catch the air better.

The Seal: Ensure your plane fits onto the launcher tube snugly enough to catch the air blast, but loose enough to slide off easily. If air escapes before the plane moves, you lose power!

The Balance: A plane that tumbles won't go far. If your aircraft flips backward, try adding a tiny bit of weight (like a penny or paperclip) to the nose to help it "cut" through the air.

Wing Stability: To keep your plane from rolling over, try Dihedral Wings—angling the wings slightly upward in a "V" shape helps the plane self-level during flight.

The Rules:

Original Designs Only: No "toy" planes, pre-made kits, or store-bought gliders. The aircraft must be an original custom creation!
The Power Source: The propulsion must come entirely from the air blast generated by stomping on a 2-liter bottle.

THE AIRCRAFT CANNOT BE HELD IN YOUR HAND TO LAUNCH

Materials: Use whatever you can find—cardboard, foam plates, straws, tape, or cardstock. Let your imagination soar!
