A Car – driven by Air

The children built a car and started a car race.

What we needed was:

·         A piece of board of a rectangular shape

·         Board for the wheels

·         2 drinking straws

·         2 cocktail sticks

·         Cord

·         The cap of a detergent bottle

·         1 Balloon

Tools:

·         Scissors

·         Glue

·         Adhesive tape

·         Pencil

The drinking straws are fixed at the board with the adhesive tape. Through the straws the cocktail sticks are pushed. At the ends of the cocktail sticks the wheels with a diameter of about 5 cm are fixed. Now the balloon is pulled as far as possible over the cap of a detergent bottle. On top of one of the axis a ca. 30 cm long piece of cord is fixed with adhesive tape. This cord is needed to fix the nozzle. Now the balloon can be inflated. The air is escaping through the nozzle and the car races can start.
