What we're studying:
We studied about energy transformations. we learned that good results comes only with hard work.

Our Team Leader's favorite quote:
"if we don’t believe that the machine is going to work ,so it will not work"

Why we think we should win:
We think that we deserve to win, because we have gone through a difficult process.
We have spent a lot of time and energy on this project. What's more we worked mostly alone with little to no resources creating all of the parts of the machine from scratch nothing was a "ready-made" . We fell that we tried to be as creative and innovative as possible, we fell that considering the effort that we put in: on class time, private time, sleep time. This can be seen in the product, we are particularly deserving.

Suggestion for next year's challenge:
Our idea for the task on next year is to open a refrigerator in the end of machine.

Favorite Rube Goldberg video:

In our machine we have to open an umbrella. In the beginning we start the machine manually. The machine is composed of something like 30 steps. We love our machine, and we had fun to work on it. We hope that our hard work on the machine will pay off.

Our Step List

1) We are going to rise a cube that holds two marbles from falling.

When the cube is up the marbles will roll down a track.(2

3)The marbles will then push a roll of scotch tape, which will roll in to a red ball and force it into children`s toy.

When the ball comes out of the toy, at the bottom, it will push another marble.(4

The marble will get onto a carved track which in turn will push another marble. (5

In the carved wood until it touches a pendulum. (6

The pendulum will cause a car with a phone – stylus to touch a phone screen. (7
Than the phone will play music that will be heard very loud from a speaker.(8
9) The speaker's vibrations will push a heavy marble into a track leading it to force a plug into a socket which will make an electrical connection causing a light to go on.

The light will heat an electrical solar panel activating a propeller.(10

11) The propeller turns around making another marble roll in a track into a cup – pushing the cup over.

The fallen cup has an attached sharing which is connected to a mini Ferris.(12

13) When the cup falls down it pulls its starting causing the Ferris wheel to turn pulling up the track on which there be a marble.
The marble continues on its path, touching another heavy marble. (14

This heavy marble is connected to omega, the cup will slide down. (15

The cup will hit another marble which will hit a plash cylinder in its path. (16

The marble go down another level in the building cardboard.(17

As the cylinder slides down he will hit a marble (18

As the marble slides down it will hit a car which be also connected to a needle (19

As the car move, the needle will puncture a balloon filled with water, bursting it.(20

21) The balloon which has been sitting on a scale now will shift the weight causing the other side to fall pulling chord attached to an upside down umbrella and will force it to open .
