How to make ocean in a bottle
Kids love science experiments and it is a great way to capture their interest and throw in a bit of education to. teaching them how to make ocean in a bottle is always a great little trick that takes almost no effort and little time or scientific knowledge. To pull off this simple experiment you will really need to get hold of one of those kids 'jumbo' test tubes. They are not made out of glass they are made out of hardened plastic and they usually come with a blue stopper/screw top.
So, how to make ocean in a bottle. Firstly this experiment is meant to be a demonstration to the kids, they can try the 'how to make ocean in a bottle' experiment themselves but only after you have demonstrated first. Purchase a smaller sized bottle of baby oil and fill the test tube up to the halfway point. The main 'ingredient' for the 'how to make ocean in a bottle' experiment is water - open up the test tube ( with the baby oil inside ) and slowly add the water until the mixture reaches as close to the top as possible.
The water in the 'how to make ocean in a bottle' experiment will instantly start to sink to the bottom of the test tube because it is more dense and heavier than the baby oil. Pick a food coloring of your choice - personally, I think red is the best color for this type of experiment. Put in a few drops of food coloring and then replace the cap. Start turning the closed test tube on it's head and watch the two substances class themselves based on density. The oil will always travel towards the top and the water will always travel towards the bottom.
The food coloring in the 'how to make ocean in a bottle' experiment is water based and because of this it will mix together with the water. This food coloring now acts as a marker for us and will show us where the water is inside the tube. Gradually turn the tube on it's head back and forth and watch the red ocean travel from one end of the tube to the next - it's pretty cool, much like one of those 1960's bubble lamps ( peace man! ).
So there we have it, how to make ocean in a bottle with minimum fuss and next to no cost - the kids will love it!
