Our step list:
1. The machine starts by that the mechanical clock that works on a coil spring that vibrates and moves a hoop. In this part it moves from Elastic Energy to Kinetic Energy.
2. The hoop moves and hits a tooth brush that is tied to a pendulum. This is a transfer of momentum.
3. The tooth brush hits a domino which is simulating a set of teeth inside the boy's mouth. The momentum in the domino causes the domino effect.
4. The last domino in the set is tied to a piece of string in which in the other end is tied to a magnet, with different polarity on the plastic path. The last domino that falls pulls the magnet.
5. The wooden brick on the rail releases by the falling magnet, it convert height energy to kinetic energy.
6. The wooden brick on the path slides and hits another brick, which blocks a type of crane which on the second side holds down the toaster's button. The transfer is once again Momentum.
7. The toaster's button holds down a spring, and when the crane releases the button, the spring releases as well. In the toaster there are 2 wooden plates which simulate toasts. When the spring releases they "jump" up and hit a plastic path with a marble on top. Elastic Energy converts to kinetic Energy and height energy.
8. The ball that rolls down the rail falls down to another path that has Tuna Cans. It hits a can and transfers momentum to it.
9. The tuna can rolls down the path and hits a Polygal type of material and gives it momentum. The material is connected to a wooden stick and the momentum is transferred to the 2nd tuna can.
10. The 2nd tuna can rolls down the path and hits a Polygal type of material and gives it momentum. The material is connected to a wooden stick and the momentum is transferred to the third tuna can.
11. The third tuna can hits the Polygal material that gives momentum to the wooden stick that hits a tennis ball.
12. The tennis ball starts to roll down the path and hits a second tennis ball, and gives it momentum.
13. The second tennis ball starts to roll down the path and hits a third tennis ball, and gives it momentum.
14. The third tennis ball starts to roll down the path and hits the last tennis ball, and gives it momentum.
15. The fourth tennis ball hits a piece of aluminium that moves it to hit another piece of aluminium and that makes kinetic energy transfer into kinetic energy.
16. The two piece of aluminium hit each other and close an electric circuit. This means that kinetic energy converts into Electric Energy.
17. The clock starts to tick and move around. The Styrofoam ball that's inside of the clock moves with it. It's a transfer of kinetic energy.
18. The ball falls into the hole inside of the clock into a vertical tube.
19. After The vertical tube the ball continue to a sloped path.
20. It then hits a small piece of domino that's tied to a wooden brick. It’s a transfer of momentum.
21. The domino falls down and pulls the brick with it. It transfers height energies. 22.The brick falls down and lets a metal ball roll down the path. Because the path slope the ball transfers it's height energy to kinetic energy.
23. The ball falls to second path .
24. The ball falls into third path and then enters a funnel.
25. After the funnel the ball enters a tube .
26. The ball enters a second tube.
27. The ball fall down the sloped path.
28. The ball hits a magnetic canon that launches another metal ball.
29. The launched ball hits a small tennis ball and makes him move and fall.
30. The tennis ball rolls down a steep path.
31. The ball enters to a wood path.
32. The ball hits a wooden brick, which rotates .
33. The wooden brick hits a tennis ball and gives it kinetic energy.
34. The tennis ball rolls down the path and hits another wooden brick that gives momentum to another small ball.
35. The small ball rolls down the rail and hits a wooden brick, which has a rope tied to it. On the second end of the rope there's a magnet tied down to it, and the magnet has a Metal ball on a rail. The wooden brick falls down and pulls the magnet.
36. The Height energy the metal ball had turns into kinetic energy when it rolls down the rail.
37. The ball finishes it's path when it gets inside a place where it closes an electric circuit. The electric circuit belongs to 3 fans on a car. It’s a transfer between kinetic to electric energies
38. The car starts to move on the rail. Its Electric energy to Kinetic energy.
39. In the front of the car there's a wooden stick which it's use is to push a wooden brick. When the car pushes the wooden brick, it’s a transfer of momentum.
40. The wooden brick has a piece of string tied to it, and on the other side of the string there's a piece of plasticine. When the brick falls down it pulls down the plasticine with it.
41. The clay blocked a marble, so when it fell down the marble started rolling down, meaning it gained kinetic energy from the height energy it had.
42. It falls down to another rail which had a wooden piece at the end of it. When it hits the wooden piece the marble that was on top of it rolled down the rail and got into a hole that the FIRST marble skipped over. It’s a transfer from Momentum to height energy.
43. the marble hits a wooden piece, rotates it and rolls on it down.
44. The marble that fell down hits a plastic part, which when it falls it makes a farther plastic part launch and hit a piece of domino.
45. The plastic part that got launch hits a set of dominos. It's a domino effect.
46.The last domino in the set has a wooden stick attached to it. When it falls down, it lets a cylinder with a marble inside of it starts rolling down. The marble inside of the cylinder makes it gain momentum, combined with height energy it already has.
47. The cylinder hits a hoop and makes it move. It's a transfer of momentums.
48. The hoop hits a small car which makes it move. It's kinetic and momentums energies.
49. The car has a magnet attached to it. When it starts moving, its gets close to a battery with 2 magnets attached to it. When it's close enough, the magnets have the same polarity, so it makes the battery move away from the car. It's kinetic energy transferred into magnetic energy that transfers back into kinetic energy.
50. The battery rolls down on an aluminum foil, which gives it electric energy by the repel of the magnetic field of the magnets and the magnetic field of the current which created. The electric energy makes the battery gain momentum and kinetic energy.
51. The battery hits a wooden part, which has a rope that is attached to another wooden part. When the battery hits it, it makes it fall and pull the rope towards it. That is a transfer from momentum and kinetic energy to height energy.
52. When the wooden part is pulled, a ball releases and rolls down a slide. Its height to kinetic energy.
53. The ball hits another wooden stick that is attached to a rope with another wooden part. When the wooden stick falls, it pulls the wooden part with it. It's kinetic to height energy.
54. The wooden part holds down a small ball, when it pulled ,the ball releases.
55. The ball hits two small tennis balls.
56. The balls fall through a plate with nails while they converts height energy to kinetic energy.
57. The balls fall into a pipe made out of paper cups.
58. The balls go out of the pipe into a tin can.
59. The tin can goes down and makes a weight that's tied with a derrick to goes up.
60. The tin can press a switch that activates an electric pump that pours out milk into the bowl.
61. The weight that lifts up makes the cereal box get an angle in which it lets out the cereal into the bowl!
Why think we should win?
We think we should win because we tried to build most of the machine by ourselves. We feel really connected to our machine and spent days and nights for the machine to get work. Furthermore, we also represented the machine to younger pupils and their parents and inspired them for the future!
Our suggestion for next year's challenge
Pour a cup of coffee.
The machines volume:
Height: 1.75 M
Surface: 3.67 M
Volume: 6.43 M
