In my Rube Goldberg I have a fooze ball which I push one of the handles which pushes a soccer ball down a ramp hits dominoes, Knocks a ball the ball falls a 3 foot drop hits more dominoes, knocks a ball into a tube hits a stack of cups with a baseball on top that has a string connected to the baseball and a soccer ball so when the baseball drops it pulls the soccer ball, and from the soccer ball I have a rope connected that pulls a duct tape bag with my phone in it down a zip line and brings me my phone.
