9. The crane releases a stretched thread tied to a spring powered toy train- elastic energy is being converted into movement energy.
10. The train moves a ball down a horizontal track- the momentum of the train pushes the ball.
11. The ball falls into a pipe- height energy is converted into movement energy.
12. The ball falls onto a heavy weight that is connected by rubber bands to the bottom of the pipe- the momentum of the ball is transferred to the weight.
13. The weight is stretching the rubber bands- the movement energy of the weight is being converted into elastic energy of the rubber bands.
14. The weight goes down and pushes the button of the umbrella- the momentum of the weight is transferred to the button of the umbrella.
15. The button activates the mechanism of the umbrella- elastic energy from the spring in the umbrella to the movement of the umbrella.
16. The umbrella opens and pulls a thread- movement energy to elastic energy.
17. The thread pulls a switch (elastic to movement) that activates a circuit which contains batteries and a fan- chemical energy of the batteries converts into electrical energy, to a circular movement energy.
18. The movement energy of the fan is converted to the movement energy of the air stream. (wind)
19. The air from the fan knocks down a set of dominos. (the momentum of the air is passed to the set of dominos)
20. The dominos knock a ball down a tilted track- height energy to movement.
21. A ball falls into a cup that is tied to one end of the threat, and makes the thread stretch- height energy to elastic energy.
22. The second end of the thread is tied to a balloon, when the thread is stretched the balloon rises- elastic energy to height energy.
23. The balloon rises and the drinking soda spills out into a bottle with vinegar that leads to a chemical reaction.
24. The balloon inflates and tilts the surface above it- elastic energy to height energy.
25. A ball rolls and hits the bottom part of a hammer- the momentum of the ball passes to the hammer.
26. Hammers built as vertical cranes that spin around its axis, with balls that roll down a tilted surface, they represent a mechanism that lifts the machine's movement continuation to a higher point, the top part of a hammer (2) hits a ball which rolls down a tilted surface- the momentum of the hammer is transferred to the ball.
27. A ball hits the bottom part of a hammer (2)- the momentum of the ball to the hammer.
28. The top of the hammer (2) hits a ball that rolls down a tilted surface- momentum of the hammer to the ball.
29. The ball hits the bottom part of a hammer (3)- momentum of the ball to the hammer.
30. The top part of the hammer (3) hits a ball that rolls down a tilted surface- the momentum of the hammer to the ball.
31. The ball hits a set of dominos- the momentum of the ball to the set of dominos.
32. The set of dominos hits another ball- the momentum of the set of dominos to the ball.
33. A ball falls to a cup that is connected by a thread to a pulley that changes the movement direction from bottom to the top and allows to lift with little force a big weight- the pulley converts height energy to movement energy.
34. The cup rises and pulls the break that holds the pump handle in the air- elastic energy to movement.
35. The pump handle goes down thanks to the rubber bands that were released- height energy to movement.
36. The air from the pump pushes a ball- the movement energy of the pump increases the air pressure inside the pipe and lets the air flow from the bottom to the top.
37. The ball rolls in a track and in the lowest point of the track the ball hits a weight and the weight falls down- the height energy of the ball transferred to movement energy, the momentum of the ball is converted to the weight.
38. The weight is being used as a part of a pulley mechanism that changes the movement direction from the bottom up and enables a small force to lift a big mass, the weight falls and pulls a thread that is tied to it- height energy is converted to movement energy converted to elastic energy.
39. The thread is stretched and opens the kettle's lid- elastic energy to movement.
40. The steam comes out of the kettle and melts the tissue paper- heat energy converted to chemical energy.
41. A weight falls from the tissue and pulls the break of ball (1)- height energy converted to elastic energy.
42. Ball (1) rolls down a tilted surface and hits domino (1)- height energy converted to movement energy.
43. Domino (1) falls and pulls the break of ball (2)- movement energy converted to elastic energy.
44. Ball (2) rolls and hits domino (2)- height energy converted to movement energy.
45. Domino (2) pulls the break of ball (3)- movement energy converted to elastic energy.
46. Ball (3) rolls down a tilted surface with a ramp on its end, it goes and comes back- height energy to movement energy to height energy to movement.
47. The ball falls down a hole and knocks down a set of dominos- momentum of the ball transferred to the set of dominos.
48. The dominos push down a weight that is tied to a coil- momentum of the dominos transferred to the weight.
49. The weight pushes the coil down a tilted surface- height energy to movement energy.
50. The coil pulls a thread that is a part of a pulley mechanism that change the movement direction from the bottom up and enables a small force to trigger a big force of the weight- the pulley system converts height energy to elastic energy and to movement energy.
51. The thread pulls a wooden plank that has a knife attached to it- height energy is converted to movement energy.
52. The plank goes down and cuts a thread that is connected to a pendulum- height energy converted to movement energy.
53. The pendulum releases and spins- circular movement energy around the axis.
54. The pendulum hits a weight- the momentum of the pendulum is passed to the weight.
55. The weight falls onto a horizontal crane- the weight convert height energy to the movement of the horizontal crane.
56. The horizontal crane activates a vertical crane system- the vertical crane system converts movement energy to height energy.
57. The crane system triggers a big vertical crane that tilts the surface that a ball is rested on.
58. The ball rolls down and hits the bottom part of a wooden plank- height energy of the ball converts to movement energy and passes down its momentum to a hammer.
59. The top part of the hammer hits another ball that rolls down a tilted surface- the kinetic energy of the hammer converted to height and movement energy of the ball.
60. The ball hits a copper plate (1) and pushes it to copper plate (2), and thus an electric circuit is activated which contains batteries and a circuit board- chemical energy converted to electric energy.
61. Electric signals pass through the antenna that converts them into radio waves, a part in the toy car receives the radio waves, the car converts electric energy to movements energy.
62. The car drives forward and pushes the disc- momentum of the car passes to the disc.
63. The disc rolls on a custom track that leans on a tilted surface- height energy converted to movement.
64. The disc hits a weight that is tied to a mechanism- momentum of the disc passes to the weight.
65. The weight falls down- height energy of the weight is converted to movement and elastic energy that makes the thread stretch.
66. The elastic energy of the thread makes a movement of a mechanism that spins on its axis, it has element of a pulley and a crane.
67. Height energy of the cereal converts to movement energy of the cereal and it spills to the bowl.
68. Another thread that is connected to a weight converts the elastic energy that is within it to circular movement energy of a mechanism that holds a carton of milk.
69. The milk carton spins on its axis, the carton is lifted- movement energy is converted to height energy.
70. Hydraulic pressure in the tube rises and makes the milk spill into the bowl right after the cereal.
