Building a Balloon Car

Challenge: Build a car that moves with the power of the balloon. Whose car can go the farthest?


Materials:
1 Balloon
4 Wheels
2 long pieces for frame
4 (or 2) pieces to attach wheels to frame (so they spin)
Pieces to keep balloon attached to car
Pieces to keep balloon off front wheels and floor







Hints and Notes
1. Your sets don’t have exactly the same pieces so you will have to find similar pieces that do the same thing.
2. The horizontal to vertical bracing - vertical beam connected to two beams with two plates between keeps the model stable. Without horizontal to vertical stability the balloon will knock off the LEGO elements.
3. Light is good. Heavy is bad.
4. Make sure your design keeps the balloon off the wheels and the floor.
5. Make sure your wheels spin.
6. Make sure your balloon stays off the wheels and floor.
7. Make sure your balloon stays attached to the car.
