Our step list:

1.    Rolling compact discs = height energy > kinetic energy.
2.    Discs hit a toothbrush in a cup = kinetic energy > kinetic energy.
3.    The toothbrush falls = height energy > kinetic energy. 
4.    The brush hits the cup turbine = kinetic energy > kinetic energy.
5.    The turbine pulls a plank = kinetic energy > kinetic energy.
6.    The plank falls = height energy > kinetic energy.
7.    The plank hits a clip = kinetic energy > kinetic energy.
8.    The clip releases a rubber band = kinetic energy > kinetic energy.
9.    The rubber band launches an arrow = elastic energy > kinetic energy.
10.    The arrow hits a wooden cylinder = kinetic energy > kinetic energy.
11.    The wooden cylinder falls = height energy > kinetic energy.
12.    The wooden cylinder hits a toy car = kinetic energy > kinetic energy.
13.    The toy car drives down the slope = height energy > kinetic energy.
14.    The toy car hits a ball = kinetic energy > kinetic energy. 
15.    The ball rolls down a board of nails = height energy > kinetic energy.
16.    The ball hits a domino block = kinetic energy > kinetic energy.
17.    The domino blocks hit each other and fall down = kinetic energy > kinetic energy.
18.    The domino block hits a ball = kinetic energy > kinetic energy.
19.    The ball rolls down multiple slopes = height energy > kinetic energy.
The ball hits a domino block = kinetic energy > kinetic energy.
The domino blocks hit each other and fall down = kinetic energy > kinetic energy.
20.    The domino block hits a doll= kinetic energy > kinetic energy.
The doll hits a block = kinetic energy > kinetic energy.
21.    The block hits a sellotape reel = kinetic energy > kinetic energy.
22.    The sellotape reel falls into a cup = height energy > kinetic energy.
23.    The cup pulls down a backgammon board = kinetic energy > kinetic energy.
24.    The backgammon board falls and spills cereals into a bowl  = height energy > kinetic energy."

Why think we should win?

Because that's our first year and we still didn't give up, we gave everything, including: stayed after school, instead of using money for the parts we searched the city. Because it's the first time in our school that it builds the amazing machine we worked without any teacher or guidance!

Our suggestion for next year's challenge

to break an egg on a frying pan

The machines volume:
Height: 1.5 M

Surface: 3.46 M 

Volume: 5.19 M
