Discussion Overview

The discussion revolves around constructing a Rube Goldberg device for a physics independent project, specifically focusing on achieving ten steps to light a bulb while incorporating various energy transformations such as potential, kinetic, rotational, electrical, light, magnetic, or stored chemical energy.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant mentions using a pool ball rolling down a hill to knock over dominos, addressing rotational kinetic and linear kinetic energy.
  • Another suggests incorporating electromagnets into the device.
  • A different idea involves using a balloon over a flask of water, where heating the water inflates the balloon to knock something over.
  • One participant proposes a more complex idea involving a scale measuring the growth of mold on bread, which would trigger a series of events including a squirrel interacting with tobacco.
  • There are suggestions to include a bowling ball and even a shotgun in the device, though these ideas may raise safety concerns.
  • Another participant discusses the possibility of lighting a fire using various methods, such as an electric igniter or flint and steel, and suggests using sterno to heat water and drive a mechanism.

Areas of Agreement / Disagreement

Participants present multiple competing ideas and approaches for the Rube Goldberg device, with no consensus on a single method or design. The discussion remains unresolved as participants explore various possibilities.

Contextual Notes

Some ideas presented involve safety considerations, particularly regarding the use of fire and electrical components. The complexity of certain proposed mechanisms may also depend on the feasibility of execution.

allright so I'm constructing a rube goldberg device as a side physics independent project and it has to go through ten steps to achieve the final outcome of lighting a bulb. i need some ideas for steps I'm drawin a blank.

it has to go through 5 different energy changes like potential, kinetic, rotational, electrical, light, magnetic, or stored chemical

some help guys?

i got a pool ball rolling down a hill and knocking over a stack of dominos so i got rotational kinetic and linear kinetic taken care of but i need 8 more steps b4 i get to the light bulb
 
Electromagnets are always good for this too.
 
You can do something where you put a balloon over a flask with water in it, then have something turn on a heater to boil the water which will inflate the balloon, which will knock something over
 
Or you could lay a piece of bread on a scale, and wait for mold to grow on and increase the mass measured which would move the scale, that would drop a piece of tobacco, then a Dave the squirrel would scamper over to the tobacco, but then he would be shocked with 10,000 volts and his temperature would go up which would...
 
Gotta have a bowling ball!
 
Ooooh yes, most important. And a shotguns.

Well, it would be defintely cool if somewhere along the line you lit a fire. Not sure how you're going to do it - light a match? Flint & steel? An electrical igniter? Or what you'll burn. Especially if you want to keep it reasonably safe.

Safest thing I can think of off hand is to light some sterno with an electric igniter that they use for model rockets.Once you get the fire started, though, you can heat a kettle of water until it bolis. THis will drive something that spins around - with enough force to turn a crank. That can lift a gate to let a ball roll out or something.

Maybe that's too complicated, but it'd be a nice classic idea.
