Seven Layer Density - Cool Science Experiment

- Check out this and other cool science experiments at www.stevespanglerscience.com/e... Everyone knows that vegetable oil and water dont mix. Thats because the two liquids have different densities. Density is basically how much stuff is smashed into a particular area or a comparison between an objects mass and volume. So, the exact same volume of two liquids may actually have different masses, so they would have different densities. Thats why vegetable oil floats on top of water.

Steve Spangler is a celebrity teacher, science toy designer, speaker, author and an Emmy award-winning television personality. Spangler is probably best known for his Mentos and Diet Coke geyser experiment that went viral in 2005 and prompted more than 1,000 related RUclips videos. Spangler is the founder of www.SteveSpanglerScience.com, a Denver-based company specializing in the creation of science toys, classroom science demonstrations, teacher resources and home for Spangler's popular science experiment archive and video collection. Spangler is a frequent guest on the Ellen DeGeneres Show where he takes classroom science experiments to the extreme. Check out his pool filled with 2,500 boxes of cornstarch!

Additional Information:
On the education side, Spangler started his career as a science teacher in the Cherry Creek School district for 12 years. Today, Steve travels extensively training teachers in ways to make learning more engaging and fun. His hands-on science boot camps and summer institutes for teachers inspire and teach teachers how to prepare a new generation for an ever-changing work force. Over the last 15 years, he has also made more than 500 television appearances as an authority on hands-on science and inquiry-based learning.
On the business side, Spangler is the founder and CEO of Steve Spangler Science, a Denver-based company specializing in the creation of educational toys and kits and hands-on science training services for teachers. The companys unique business strategies and viral creations have been featured in the Wall Street Journal, Inc. Magazine, Wired and TIME Magazine where online readers voted Steve Spangler #18 in the Top 100 Most Influential People of the Year for 2006 (what were they thinking?). You'll find more than 140 Spangler created products available online at SteveSpanglerScience.com and distributed to toy stores and mass-market retailers worldwide.
Spangler joined NBC affiliate 9News in 2001 as the science education specialist. His weekly experiments and science segments are designed to teach viewers creative ways to make learning fun. His now famous Mentos Geyser experiment, turning 2-liter bottles of soda into erupting fountains, became an Internet sensation in September 2005 when thousands of people started posting their own Mentos explosions on RUclips.com.
As founder of SteveSpanglerScience.com, Spangler and his design team have developed more than 140 educational toys and science-related products featured by mass-market retailers like Target, Wal-Mart, Toys R' Us, Discovery Channel Stores and over 1,400 independent specialty toy stores. His educational science catalog and on-line business offers more than a thousand science toys and unique learning resources. Recently, Spangler has been featured in the Wall Street Journal, Inc. Magazine, WIRED, the History Channel, Food Network and TIME Magazine where on-line readers voted Steve Spangler #18 in the Top 100 Most Influential People of the Year for 2006.
His recent appearances on the Ellen DeGeneres Show have taught viewers how to blow up their food, shock their friends, create mountains of foam, play on a bed of nails, vanish in a cloud of smoke and how to turn 2,500 boxes of cornstarch and a garden hose into a swimming pool of fun.
I had to watch this video for our science density assignment today, and this looks super cool
same
Same
SHAKE IT!! SHAKE IT!! SHAKE IT!!
i made a science wxperiment like this. but with all water
I haven't watched this yet.
Have I?
I don't know.
I can't remember when I started watching these.
This is a perfect illustration of buoyancy!
I tried this it worked thanks Steve
i cant stop watching these videos o.e
Bom Dia e domingo para todos!
Try it!
I want to make a 2 layered snow globe. What liquid can I use that is denser than water and does not dissolve into the water after giving the snow globe a shake?
if you pour it into the beaker fast, would it mix?
@shajidh2o It would eventually reset itself back to the way it was before you shook it. If the layers are each less dense than the layer below them, they shouldn't mix.
If you shook it up would it all re seperate? or would the soap/water mix?
i have to do this in school lol
How do you get the Corn starch to be liquid?
That's cool
can i ask sir ?? uhmm how to color the rubbing alcohol ??
can you put something and sumberge it, as it goes down it crushes just like the ocean?
@mcwario13 yes nail polish remover is but what about methilated spirits or something?
my 3rd grade teacher loves science and he did this with us and we called it the liquid birreto
You Forgort "That Is phenomenal"
can you do the same exsperiment and then turn the hole thing upside down! ;P
whould be cool to see
Instead of that instrument he's using (tur(n)key baster? I'm Dutch, so don't know this thing) to suck up the fluids and then gently putting it in the big glass you can use a sheet of paper and turn (fold) it into a 'beak' to pour out into the big glass whatever fluid you want to use
wouldn't the food colouring make the oil or whatever substances more dense than it originally is?
You would need one really strong freezer to freeze that.
Water = 0 celcius (32 F)
Lamp oil = -30 celcius (-22F)
Rubbing alcohol = -89C (-128F)
Yea I was going to ask if you put the contents a different order would they settle in the right order?
Yea
its not another reason they don't mix, it is the reason they don't mix. There is a mistake in the description. Different densities don't determine whether of not things mix, what you just described determines that. Alcohol and water have an even larger difference in their densities than oil and water and yet they mix just fine
I think they would all mix. Soap has a hydrophobic end (the polar carboxylate ion) which is water soluble.
We tried that in my science class and It all mixed. But a few weeks after we saw it and the water and oil separated again.
Steve unless your using something other than isopropyl alcohol, rubbing alcohol's density is not .87 g/cm3 its actually less than .8 g/cm3
@JackRabbit894 Actually it probably wouldn't, at least not completely. Mixing or dissolution in this case, is not related to density. By shaking you would get all the fluids in contact and some of them would dissolve in others. For example honey, syrup, alcohol, and a dish soap to a certain extent, are all soluble in water, so they would partially mix.
shake it up!
one more video and i'll sleep i promise.
can you build colors like first put red water at the bottom then put oil on top then put green water then oil then but blue will they stack? please reply ASAP!!!!!!!
you can mix them and they would unmix them self
There is also another reason why the substances do not mix. Some of the substances are polar and some are not. Water is polar and oil is not polar for example. Only substances that are polar mix with polar substances and same goes for nonpolar substances.
CANADIAN SQUIRTGUN!!
@shajidh2o
it wouldnt because they all have different densitys so it wouldnt evenlast if u tried
Emulsion?
The polar liquids(water, alcohol, soap) would mix, and the non-polar (the oils) would mix.
The organic complex liquids(honey, syrup) would mix with both, to a lesser extent.
End result: Muddy soapy syrupy water on bottom, muddy oily stuff on top, some sludge at the bottom and scum on the top.
I.E. Quite a mess.
Now throw it in the ocean haha!
mix a 70/30 ratio 70 being water and 30 being corn starch boil it on the for about 1 hour
Get some fluorinert steve. Then you'd have an 8 layer density :)
Now clog the top and turn it upside down
It will pour into the other layers and make a gross looking brownish green color, and you would have to wait for it to seperate again before you could add anything else.
kool
light it
would the blood of my enemies work as well?
Haha same, we did this in science.
Oils in the top of water so it's lighter. Facepalm
SHAKE IT O.o
It would stay the same:) It would not mix because of its denstiy:)
dump a lit match in it after this.
corn syrup
The soap would mix with the water..
probably just food dye
it will "mix" then separate again.
@thatguyzoidberg Need a username? Why not Zoidberg?
pretty old

weird
It's not in middle school
