Our step list:
1. A weight falls through an inclined tube and hits a car.
2. The car gets pushed, which opens a basket and pulls a ruler that is holding a wheel.
3. When the ruler is pulled, the wheel starts to move by a weighted sack that is pulled down.
4. The weight, when it falls down on a book that is wrapped with tin foil that is lying on a swing, closes an electrical network.
5. When the electrical network is closed, it turns on a fan, a siren, and a flashing light.
6. The fan pushes a boat with a sail that starts to move.
7. When the boat finishes its path, a stick that is attached to it, pushes a big wood domino.
8. This domino falls down on more dominos.
9. The last and the biggest domino push a power ball.
10. The ball falls on a slide that is on an axle that is build from a metal rod and tw wheels.
11. The ball slides down and hits a hinge that is made out of two tires attached to a metal stick.
12. Then a hinge spins and pulls a string that releases a brake on a tennis ball.
13. The ball slides down a slide that is fenced by nails, and then hits a book with a cup of baking soda on it.
14. The book falls and the soda is spilled into a can filled with vinegar. A chemical reaction between them makes bubbles.
15. The solution overflows into a track that holds a marble.
16. The marble has potential energy that transfers into kinetic energy causing it to start rolling down the track.
17. The marble then hits a tennis ball that is attached to a bigger track.
18. The tennis ball descends down the track and hits a trampoline. The elastic force of it makes it jump and falls right into a basketball hoop.
19. In the hoop there is a swing with a string attached to it.
20. When the ball hits the string it shakes another track.
21. On the track is a marble that starts to roll after the shake.
22. On the edge of the track is a hinge that is connected to a wooden plank. Attached to the wood is an open band aid.
23. The marble hits the top of the wood, the wood falls and sticks the band aid to the doll.
