Project by Harry & Daxton & Andrew

Steps:

A. Roll a ball into a inclined plane tunnel.

B. The ball triggers a marble to fall down from a small bucket.

C. Marble slides down and hits dominos.

D. Dominos hits a button of a toy chest, which triggers it to open abruptly.

E. The top of the toy chest hits a stick that supports metal marble.

F. Metal marble falls due to its gravitational energy.

G. Metal marble lands on lever, and a bouncy ball on the other side of the lever bounces.

H. The bouncy ball shoots into a cup, and due to its mass, a pulley pulls up the other side.

I. The cup hits a wooden hammer.

J. The wooden hammer hits space bar of laptop, which calls a phone.

K. A phone rings and drops down the inclined plane.

L. Phone hits toy car to move forward.

M. Toy car goes through timing gate and hits mouse trap.

N. Mouse trap drops on top of a plastic mouse.

Electrical

Energy Transfers:

1. Mechanical (Ball rolling through a tunnel) -> Mechanical (Hitting tiny bucket containing marble)
2. Mechanical (Marble comes out of the bucket) -> Mechanical (Marble rolling down inclined plane stairs)
3. Mechanical (Marble slides down) -> Mechanical (Marble hits domino)
4. Mechanical (Domino knocks down) -> Mechanical (Domino hits the button of toy chest)
5. Elastic Potential (Spring inside toy chest is compressed) -> Elastic Kinetic (The spring abruptly stretches out)
6. Mechanical (Cover of the toy chest hits supporting stick) -> Mechanical (Shakes the top and triggers a marble to move)
7. Gravitational (Marble falls into holes) -> Mechanical (Marble uses its gravitational energy to hit lever)
8. Mechanical (Lever shoots marble up in the air) -> Gravitational (Marble drops)
9. Mechanical (Marble rolls) -> Gravitational (Marble drops into a cup)
10. Gravitational (The pulley pulls up the other cup) -> Mechanical (The cup hits horizontal stick)
11. Gravitational (The stick falls on top of space bar of laptop) -> Mechanical (Tip of the stick hits the space bar)
12. Chemical (Battery sends electrical energy to laptop) -> Sound (Laptop starts call to a phone, which makes the phone to ring)
13. Chemical (Battery sends electrical energy to laptop) -> Electrical (Triggers phone to light up)
14. Chemical (Battery sends electrical energy to laptop) -> Mechanical (Phone vibrates and falls down the inclined plane)
15. Mechanical (Phone moves down the inclined plane) -> Mechanical (Phone hits toy car to move down another inclined plane)
16. Mechanical (Car hits mouse trap) -> Gravitational (Mouse trap falls to trap a mouse)
