Bright Idea (Possibly)

2. Overview
Water falls down a ramp and falls into pipe balanced at its center of mass which knocks a ball down another ramp.
It then hits a cork acting as a pendulum which swings and hits another marble.
That marble then rolls down a ramp and collides with the final marble which acts as a trap door making a lightbulb turn on.

3. Equations Used in Project
Conservation of Energy
mgh = 1/2mv^2 + 1/2I^2
Torque
 = Frsin
Center of Gravity
R = (m1r1 + m2r2)/m1+m2
Angular Momentum
Ib*b = Ib*b + Ic*c

5. Conclusions
Each teammate showed up to every group meeting, supplied materials, and gave 1000%.
We hope to “light up” the audience with our Rube Goldberg
