Ocean in a Bottle
Intro: 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
What you'll need:
-->a plastic bottle {I'd recommend 1 liter or smaller for weight's sake}
-->water
-->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}
Optional:
-->scissors
-->electrical or duct tape

STEP 2: Adding the Water
Once you have your materials, remove the label from the bottle. You may need scissors for this. Or not.
Next, fill the bottle about half way up with water and decide what color you want it to be. I was out of red and yellow, so I settled on a teal hue (two drops green, three blue). Add the food coloring and give the bottle a light swirl to mix.

STEP 3: Oil Time
Here's where that funnel is going to come in handy.
Slowly fill the rest of the bottle with your oil. The funnel with prevent the oil from getting all over the outside of your bottle and rendering it hopelessly slippery (I know from experience). Come as close to the top as possible without spilling.

STEP 4: Seal It!
Now to seal in the goodness.
Basically you're just going to screw on the cap as tight as you can. I put some glue on the threads of the bottle before closing as added insurance.
You can also wrap some electrical/duct tape around the cap as further protection against leaks if you feel so inclined.

STEP 5: And Enjoy (plus Variations)
Ta-da! Rock, tilt, and shake the bottle to enjoy the fascinating, elegant wave patterns.
Variations:
-->I used a fairly large plastic bottle for demonstration purposes, but a smaller and/or a glass bottle
would be fun to try this with.
-->You could color the oil instead of the water; I just don't remember how.
-->Maybe throw some glitter or something in there. Who would dare stop you?
Have a good time!

You can also use turpentine in place of oil.

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

I recommend NOT using vegetable oil. It can spoil and turn rancid. We made an ant barrier for my mother's hummingbird feeder, and she filled it with olive oil the first time. Some few months later, ants invaded the feeder and investigation revealed that the oil went rancid, turning thick and gelationous... the ants could then walk right across it! After cleaning it up and refilling with mineral oil, it generally lasts at least a year before getting too full of miscellaneous debris and needing to be cleaned and refilled again, but the mineral oil remains liquid.

...of course, being sealed in a plastic bottle will keep air and microbes from getting to the vegetable oil and it might last a really long time if you're lucky. But unless you sterilize everything and work very carefully to keep it that way, there's no way to be sure.

For multiple layers you need:
#1: hydrophobic liquid that's less dense than water
#2: water
#3: hydrophobic liquid that's denser than water. This is the tricky one. I've seen tetrachloroethylene recommended for this purpose on DIY lava lamp websites, but it's also bad for you, so you would need to do this whole thing in a glass container AND make sure the container never breaks. https://en.wikipedia.org/wiki/Tetrachloroethylene
