Our step list:

O1. stretching a spring - elastic energy

2. releasing of the spring - kinetich energy

3. conservation of momentum - flying arrow hits a ball

4. kinetic potential - the ball rolls down a track

5. wave kinetic potential - the falling of dominos

6. kinetic potential - pressing the trigger of the computer

7. electrical energy - the computer plays a music file.

8. electromagnetic energy through bluetooth - GBL starts playing the music

9. magnetic field - from electric to potential - a ball moves on the speaker

10. from potential to kinetic - the ball rolls down a track

11. from potential to kinetic - an iron ball rolls down the track

12. from potential to kinetic - the ball falls on a small can

13. from potential to kinetic - moment which causes energy and lifts a cork

14. from potential to kinetic - water flows into a hole

15. conservation of momentum - the water turns a vane

16. from potential to kinetic - a wire is pulled up

17. from potential to kinetic - baking soda falls into a bottle - gravitation

18. chemical reaction - baking soda mixed with vinegar

19. outcome of chemical reaction CO2 - the capacity of the balloon rises

20. motion - the balloon pushes a ball

21. motion releases a barrier

22. from potential to kinetic - a toy car pushes the cornflakes box

23. from potential to kinetic - the cornflakes spills into a bowl.

Why think we should win?

We are team consisting of two city schools. The students worked together very well and our machine is very creative.

Our suggestion for next year's challenge

shooting an arrow

The machines volume:
Height: 1.2 M

Surface: 4 M

Volume: 4.8 M
