Introduction: Stacking Liquids: Home Experiment

An easy home experiment; create a tower of liquids. The liquids near the bottom are more dense while the objects on top are less dense. This can also be used to determine the relative density of solid objects. Place them in the container and see where they float.

This is great!
I think I will surprise my wife, And make something artistic for once, Rather than another Frankenstein's Lab experiment.  I plan to let it sit for a long time, Possibly years, So that should answer my questions.
Thanks again.

I've always wondered where to get this information.
Your video is straight to the point, Narrated nicely, And no longer than absolutely necessary.
Very nice work.

I would like to see some of the things you have made, And possibly you could answer a few questions.
How long will these chemicals last in the container?
Will they eventually mix?
Would creating a vacuum help them last longer?

Thank you for your compliments!

I will definitely continue to add more videos.

Some of the chemicals will last longer than others. The oil and water will stay separate forever. If you just put the two of them into a container and sealed it, they would not ever mix.

The alcohol would evaporate if it is left uncovered, and it would mix with the water if you shook the container. However, If you kept the container covered, and had a layer of oil between the water and alcohol, it would probably last for a very long time.

I don't really think that molasses will go bad, but it MAY eventually mix with the water, I have never left it out long enough to find out. I think it would take quite a while, though. I think I left that one on my desk for a week before I cleaned it up, and it was still fine.

The soap layer WILL mix if it is left with the water for too long...

So if you want to make it last for as long as possible, I would stick to water, oil and alcohol. Then put a lid on it and make sure you do not shake it. Hopefully that answers your questions! I realize this response is ironically longer than the video... :)
