Balloon Powered Egg Carton Car

To build your own balloon powered cart you will need:

Two drinking straws,

two barbecue wooden sticks,

four plastic bottle cups,

one egg carton,

one balloon.

How to make your balloon powered car:

1. cut the egg carton in half,

2. cut one of the straws in half, and attach each half with duct tape to the bottom of the egg carton, see the picture below,

3. push the barbecue sticks through the straws,

4. puncture a small hole in the middle of the plastic bottle cups, and put them at the end of the sticks,

5. tape the balloon with the duct tape to the second straw, see the picture below,

6. attach the straw with the balloon to the top of the car.

Your car is ready to go.

Blow the balloon, and put the car on the floor.  The air coming out of the balloon will move the car forward.
