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 1Dicide 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.

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.

Nov 26, 2008. 1:35 PMmg0930mg says:

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

Nov 26, 2008. 4:02 PMBartboy says:

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

Mar 3, 2009. 2:20 PMmg0930mg says:

So, do one.

Wasagi says:

Wait, how does it strt? Does the dog trigger it or do you?

Mar 19, 2008. 4:11 PMTeacherOfTheWays (author) says:

you pull the string which sets the thing off.

Mar 22, 2008. 4:49 PM

Wasagi says:

Hmmm, if you could train a dog to set it off, that would be pretty cool... Awesome device!

Nov 30, 2008. 9:38 AMget to da parakeet says:

wat is the song in the beginning called?

Nov 30, 2008. 9:40 AMget to da parakeet says:

But it is cool.

Nov 26, 2008. 11:56 AMAnarchistAsian says:

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

Nov 26, 2008. 1:35 PMmg0930mg says:

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

Nov 26, 2008. 2:05 PMAnarchistAsian says:

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

Nov 26, 2008. 2:47 PMmg0930mg says:

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

Nov 26, 2008. 5:45 PMAnarchistAsian says:

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...

Nov 26, 2008. 6:05 PMmg0930mg says:

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

Nov 26, 2008. 6:54 PMAnarchistAsian says:

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

Nov 26, 2008. 7:00 PMmg0930mg says:

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.}

Nov 26, 2008. 8:06 PMAnarchistAsian says:

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...

Nov 26, 2008. 8:18 PMmg0930mg says:

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

Nov 27, 2008. 9:02 AMAnarchistAsian says:

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...

Nov 27, 2008. 9:50 AMmg0930mg says:

Yeah, I hate scheduling.

Nov 27, 2008. 10:07 AMAnarchistAsian says:

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

Nov 26, 2008. 6:58 PMmg0930mg says:

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

Nov 26, 2008. 8:05 PMAnarchistAsian says:

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?

Nov 26, 2008. 8:17 PMmg0930mg says:

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

Nov 27, 2008. 9:00 AMAnarchistAsian says:

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

Nov 27, 2008. 10:36 AMmg0930mg says:

Yeah, I'll put my plan up soon.
