Introduction: Rube Goldberg Dog Food Dispencer

Picture of Rube Goldberg Dog Food Dispencer
This is a Rube Goldberg Dog Food Dispencer that my friend and i made for a science project. It consists of over 28 steps and it is huge. I put it on instructables to share my Rube Goldberg Machine and to help you make your own.

Here is ours.

Step 1: Dicide on Parts

Picture of Dicide on Parts

I picked a pulley because we had to use the five simple machines.
Then some books, for good measure.
Then a wheel down a inclined plane.
Then a ring slide.
To the hotwheel tracks.
Then some dominoes.
More dominoes.
To a car. Then a catapault. Then a rollercoaster.
To a marble run to a cup. Then pour the food.

Step 2: Many Steps or Few Steps

Picture of Many Steps or Few Steps

You can use as many steps as you want.
Here they all are in order.
Pull pulley. Which knocks books over. To hit wheel down ramp. To hit ring slide. To hit marble. To hit dominoes which hit mousetrap to release car which launches catapault. To throw ball to hit mousetrap. That releases rollercoaster to hit marble run which knocks marble down run into cup. Cup slides down hitting dominoes. Setting off mousetrap to tip cup to pour the dog food. PHEW!



Make your own Rube Goldberg Machine and video it!!!

Try to use as many steps possible making sure it works alright.

Have fun!

wouldn't the end noise scare the sh*t out of the dog?


coolfolder (author)2010-07-25

what is the song in the see it in action part?

Hiyadudez (author)2009-01-07

This is awesome and everything, but in real life, wouldnt you just get a box of dog food and pour it in the bowl lol? :P

your missing the point. It is a rube goldburg machine, so it doesn't have to be practical.

it just has to be fun!

lemonie (author)2007-05-06

Cool! and you got some K'NEX in there too.
Also known as a "Heath Robinson" machine.

I didn't know that.

Bartboy (author)2008-08-01

Please make an all knex rube goldburg machine.

mg0930mg (author)Bartboy2008-11-26

Why don't you? Isn't that what instructables is for? Try to show us how to do it?

Bartboy (author)mg0930mg2008-11-26

Well, a knex rube goldberg machine is just a ball machine, basicly, with no lift.

mg0930mg (author)Bartboy2009-03-03

So, do one.

daninja (author)2009-02-20

hey i read frankenstien!

Hiyadudez (author)2009-01-03

Hey, isn't this a exact copy of Ur domino knockers?

yes it is. very nice job!

get to da parakeet (author)2008-11-30

wat is the song in the beginning called?

But it is cool.

AnarchistAsian (author)2008-11-26

i'm making one of these for science class too, but we make it to pop a balloon, instead...

mg0930mg (author)AnarchistAsian2008-11-26

I could help make a design, with you...

AnarchistAsian (author)mg0930mg2008-11-26

nah, it's ok, my dad will help... thanks for the offer!

mg0930mg (author)AnarchistAsian2008-11-26

Yeah, I want to make one just because...

AnarchistAsian (author)mg0930mg2008-11-26

but then you wouldn't have one, just a design... make one for yourself! make an ible! There aren't enough rubes on this site...

mg0930mg (author)AnarchistAsian2008-11-26

True, I'll do it hen I have time, and pick up some materials.

AnarchistAsian (author)mg0930mg2008-11-26

i think i want to use some of that acryllic sheet i got, and make it triggered by a coin.

mg0930mg (author)AnarchistAsian2008-11-26

What will it do in the end. That's my problem, I need to figure this part out.

AnarchistAsian (author)mg0930mg2008-11-26

It will obviously move something... mine will move a pin into a balloon... Yours could uhh... um... SHOOT AN AIRSOFT GUN! yeah, that would be LIEK SO AWESOME, YA KNOW MAN?

mg0930mg (author)AnarchistAsian2008-11-26

I was actually thinking about making mine shoot a paintball gun or making it flip a quarter.

AnarchistAsian (author)mg0930mg2008-11-27

GO FOR THE PAINTBALL GUN!!!!!!!!!!!!!!!!!!!!!!!!!!!

mg0930mg (author)AnarchistAsian2008-11-27

Yeah, I'll put my plan up soon.

mg0930mg (author)AnarchistAsian2008-11-26

I'm probably using the cheap route for mine, things around the house. Aluminum cans, paintballs(or marbles) Cardboard, possibly shoes, weird quirky, cool. It will be cool very cool.

AnarchistAsian (author)mg0930mg2008-11-26

acryllic is suprisingly cheap, but yeah, stick with that... but first, ask your science teacher if you could get extra credit for it or something...

mg0930mg (author)AnarchistAsian2008-11-26

It sucks , we have block scheduling meaning we have social studies for 2 marking periods, then science for 2 marking periods. I'm in social studies right now, no problem though, my teacher is hot. XD

AnarchistAsian (author)mg0930mg2008-11-27

ha ha *jealousy*, my teachers are either old, guys, or just plain ugly... huh, that's weird, we just have A days, and B days...

mg0930mg (author)AnarchistAsian2008-11-27

Yeah, I hate scheduling.

AnarchistAsian (author)mg0930mg2008-11-27

yeah, yours makes no sense, by the end of the year, you'll forget it all... we just split up the week...

rocketbat (author)FrenchCrawler2007-05-08

they were cool! but that second one nearly made me loose my will to live, with that thing they kept saying!

YEah they totally ruined it by that stupid jingle. can i strangle them homer-simpson-style?

Pythagoras Switch(actually, ピタゴラスイッチ or "Pitagora Suitchi") is a Japanese children's program. Most of the Rube Goldberg bits are the 'back from commercial' clips. Yes, it's annoying, but considering how annoying most US kids show music is, and how annoying J-Pop can get, the jingle is actually not nearly as bad as should be expected. :-) The jingle is saying "Pitagora Suitchi", aka the show's name.

If you really want to be annoyed by the show's music, and yet have a great laugh, check out their Algorithm March!

AnarchistAsian (author)2008-11-26

Clayton H. (author)2008-11-22

Ahh,the magic of hard work turned into a few seconds of enjoyment.

ILIKEPIE333 (author)2008-11-08

what grade did you get on the project?



PizzaPlanet (author)2008-06-27

Didn't quite catch all of the vid, but cool concept though, impressive!
