Picture of Ocean in a Bottle
An ocean in a bottle is fairly quick and simple to make. Since "quick & simple" is my middle name, this project was one of my favorites as a kid. Five minutes' work will yield an attractively hypnotic "ocean." It's also a fun use and a second chance for an old plastic bottle.

This is my first instructable--suggestions welcome. Onward--->

Step 1: Materials

Picture of Materials
What you'll need:

-->a plastic bottle {I'd recommend 1 liter or smaller for weight's sake}
-->food coloring
-->mineral oil (any oil will do, but this one is nice n' colorless; it can be procured at a drugstore for
a reasonable price)
-->water insoluble glue
-->a funnel {not pictured}

-->electrical or duct tape

Nice build. Captain Morgan bottles work great because of the etched ship. I'm gonna try to make one of these with the ship inside. I challenge someone to make an instructable for that.

Ah, just came across this. I'll need to get some mineral oil and a decent sized bottle then, and some food coloring!!! Thanks for sharing! :)

so basically you will have to get everything needed...

Yes, lol. Still haven't gotten them yet. School's starting and I'm getting busy. XD

You can also put on little toy dolphins and such to make it more interesting for the little ones!

My daughter is off school today (gas leak!) I think we'll make this today. What might stabilise the oil to prevent it becoming lots of little globules if shaken too hard? - or has anyone found what type of oil serves best?
Excellent question, and one to which I wish I had the answer as well! I had one of the store bought variety on my desk one time and someone came up and shook it. As they were shaking it, they asked what happens if someone shakes it!!! Ijit! I told him he had to buy it from me then! It was never the same after that: the oil and water never completely separated, and the little bit of air mixed with the oil permanently as well. If you get an answer, let the rest of us know!!! Please!

maybe you should leave the bottle there for a hour at least. i used veggie oil and it works for mine.

Awesome and lolz at batman not requrired

I think you could color the oil by melting some crayon

Ahh, I remember doing these with my mom back in grade school. It was so fun! I still have one of them. We put a bunch of little beads in it so they'd float, and I loved playing with it. Now, grown-up me wants to use the concept for something similar but entirely different... Filling little craft store apothecary bottles to wear with a ren-faire outfit as potions on my hip... *grins*

Running across this just makes me want to do it even more!

Cool idea. At first I was like "Uhh.. Oil doesn't Mix with water" But now I see what you were doing. Good job!

How do you keep the color from leeching into the oil? Every time I make one of these, the color from the water messes with the color of the oil after several shakes. Is there a way to prevent this?
can u use ink?
Anything is fine, I think. Just for colour.

You should make a miniature boat out of something that floats in water but sinks in the oil and put a weight on the bottom of the boat so it will be right side up.
hey thanks! its useful

use multiple types/layers of oil
I dunno if u could use more than 2 types since water oil don't mix due to density AND polarity... there's only polar (e.g. water) and non-polar (e.g. oil)...so the two that were both (non)polar they might just mix once u shook it up (even if they had different densities)... but like i said i dunno... :P
i've seen multiple layers of oil/other substances stacked...
fire_weasel (author)  Sandisk1duo6 years ago
Good idea! I may have to try that...
only i don't really know what oils you could use...
or you cold use other liquid of different density, such as corn syrup, water, oil, vinegar, ect...
that too
this is cool! you should have used the "water bottle funnel" ahahahahaha wait...that wouldn't work....xD
actually, if the densities were different enough it could...In SLO-MO!!! That would be AWESOME. But if u mean the construction wouldn't work then idk- if it was water and something u could do it underwater like in a bathtub...Actually come to think of it, i think I'm thinking of when u tape 2 bottles together and make whirly pools...dang it.
Gift Idea!!!! TY TY TY!!!! :D

That's nice, but I had the experience that when you move the bottle a little too enthusiastically, you make thousands of tiny bubbles out of the oil, and that does not look cool, and it does not happen in my soap dispenser, how do you avoid that from happening (besides not moving the bottle at all)?
