Our step list:

1. Let's Go!! And cut the wire.

2. The wire was attached to a weight->The weight  falls  and opens both sides of the curtain.

3. The opening of the curtain removes an obstacle which is blocking the cone, and turn on the laser lite

4. The cone with a ball inside, starts to roll upward . ( the central mass goes down)

5. The cone hits the funnel.

6. The marbles inside the funnel, start to roll downwards to the track.

7. The marbles hit a bigger ball

8. The big ball falls into the bucket, and the bucket starts falling.              

9. The falling bucket is tied to a round surface with a prism on it.

10. The prism rotates and the laser changes its direction (Snell's law)

11. The laser beam hits the light detector, and a switch turns on a fan.

12. A fan blows air and a parachute elevates and hits the sandglass.

13. Sand pours out of the sandglass into a wind turbine.

14. The sand is then collected into a bucket.

15. The weight of the send closes a switch.

16. The Switch disconnects the power to an electric magnet. And the magnet stops working .

17. A weight connected to the electric magnet is released and hits a wooden board.

18. A plastic ball mounted to the wooden board is released and starts falling.

19. A string connected to the board is released and a banner opens.

20. The ball is the first ball of a Newton's cradle, this ball pass all his energy to the last ball.

21. The last ball of the Newton's cradle hits a box.

22. A weight tied to a wheel falls from the box,

23. A wheel is tied to a crane, as it turns it turns the crane

24. A weight is tied to the crane, when the crane reaches the right point, the weight falls into a toy truck.

25. The truck starts rolling down the slope

26. The truck hits the mousetrap and the spring is released.

27. An airplane tied to the spring is released.

28. The airplane is tied to a weight, and is pulled up as the weight goes down .

29. The airplane tilts a track with a ball and the ball falls into a bottle.

30. The weight of the ball tilts another track with a truck on it.

31. The truck falls in reverse and releases a weight which spills a bottle of water into a tank.

32. The water rises and covers a tube and starts flowing out the tank. (because of  Differential pressure)

33. The water flows to a funnel and fills up a water tank.

34. The weight of the tank causes a hammer to drop.

35. The hammer pulls the trigger of a missile on a spring, which is in a tube.

36. There is a square bandage at the end of the tube which is then stuck to a board .

 

The End!

Why think we should win?

1.    Our mashine applies to all the competition rules without a doubt. 
2.    The mashine is good looking, compact and is built within a frame that defines accurately it’s dimensions.
3.    The mashine presents many physical principles:
•    Hydrodinamics process
•    Snell law (linear optics laws)
•    Usage of electrooptics (the modern part of science)
•    Usage of electromagnetic phenomena’s
•    Passages of different mechanic energies
•    Impulse preservation law
•    Usage of the golden rule of mechanics

4.    The physical proceses of the mashine doesn’t repeat itselves.
5.    The final mission – putting the bandage on it’s place – is comlited accurately without a doubt.
6.     The mashine has a great educational value – children who participated in the building process learned a lot about applied physics.
