Our step list:
1.one person closes the toster
2. The rope that is connected to plate pulls it up via potential and kinetic energy
3. The ball under the plate gets out and goes between the two rolling pins , onto the dishes till it hits the third rolling pin ( this produces fraction + heat+ potential + kinetic energies)
4. The rolling pin hits eleven pudding boxes
5. They hit the car with a pen on its front toward the phone
6. It activates the speaker and plays a song
7. The speaker sends vibrations via sound energy to the box on it a plastic bag .
8. The plastic bag is filled with cetric acid and sudiom bicarbonate and water so the vibrations shakes it and makes a chemical reaction that makes the balloon blow.
9. The balloon lefts the passage that has a ball on it and make it roll toward the wall and back to the left side
10. It hits a roller that will hits the ball ( this action happens five times)
11. Until the last ball gets into the box that is hung on the bicycle wheel
12. The weight of the ball makes the wheel goes round till the cornflakes in the box falls into the plate that is on the table.
Why think we should win?
We think we should win because of our team work ; and our strategy and by dividing to groups that every group has its own work to make this machine successful .
we believe in ourselves, and we believe that we can do it as long as we insist on doing it together.
Our suggestion for next year's challenge
Our suggestion for the next year’s challenge is to make machine at the end it throws a ball into a basket!
The machines volume:
Height: 2.1 M
Surface: 8.4 M
Volume: 17.64 M
