3. Intro
Purpose: To break an egg into a waiting skillet using a highly inefficient, but very cool machine.
Reasonable assumptions: All losses, friction forces, and uncontrollable variances ignored.
Procedure: Read on!

4. Special Features The process starts and ends in the same place
The machine is designed with simplicity in mind, so that its results are easily duplicated.
It is modular, because of the necessity of transporting it to and from Estabrook.

5. Phase One Frying pan is set on the lever.
Center of mass of the lever shifts.

6. Phase Two
The string and pulleys change the direction of the lever’s pull.

7. Phase Three Marble gate is lifted and releases the marbles.
Gravitational potential energy is converted into kinetic energy.

8. Phase Four
Kinetic energy of the marbles converted to potential energy as they land in an elevated cup on the end of a center of mass lever.

9. Phase Five
Marbles shift the center mass of the 2nd lever, releasing the string trigger.

10. Phase Six
The lever releases a swing arm, which has tension acting on it from rubber bands and the string trigger, turning elastic potential energy into kinetic energy

11. Phase Seven
The balloon is popped and the egg falls into the frying pan, with gravitational energy being converted into kinetic energy.
