I am doing that experiment because I have some school but it's coronavirus so I only do on line class and my science teacher weird making a video then we're gonna send it to my online Class
Wow! Thank you, this is so helpful and kind of you to make! I really appreciate the endless effort you put into this video. Thank you for having incredible animosity and truly taking care of everyone with this piece of effort filled media. Thank you.
Thanks for the brief explanation of density! It's crazy how many videos are out there that show the density tower with no explanation. Yours was great and easy to comprehend!
You may want to re-watch the portion of our video with the cartoon animations because that section explains the experiment. If a liquid has more molecules (or larger molecules) than another liquid, it will sink below the liquid with less (or smaller) molecules. Try to think of it like placing marbles in a bag above feathers, if you shake the bag all the marbles will drop to the bottom because they are heavier than the feathers. There are other forces taking part but this is the basic concept.
I did this experiment with my 9 year old son with a lesser number of liquids and it came out very well. But I have a question regarding the liquids and the order in which they are poured. We used the liquids as mentioned: Honey - 1.42, Light Corn Syrup - 1.33, 100% Maple Syrup - 1.37, Milk - 1.03 and Dawn Dish Soap - 1.06. Based on the above numbers it seems like its not a most dense to least dense order of stacking. Its seems more like its alternating. Could you explain what the logic or science behind the order in stacking the liquids are?
if u guys poured honey at last then honey will stay at the top or it will travels through other fluids and stay at the bottom is there anyone to answer this question
Yes it won’t but it’s still a problem since it will hurt anything that come near the surface which is a problem for animals which go in water and breath air.
The syrup and chocolate sauce are very close to the same density. What you see mixing in our experiment is the brown food colouring in the chocolate sauce, bleeding into the syrup and colouring it brown. The sauce and syrup actually stay separate. What else about this experiment is causing you confusion? If you describe what you are having trouble with then I am more than happy to help you out.
For a school project, I was planning to do something like this. I would rather density layer than only use the sugar technique I've seen in other videos, the colors I need to use are green, white, pink, blue, red, purple, and yellow. What substances would you recommend for good layering? It would help a lot!
the reason why your chocolate syrup mixed was because your brand was made artificially and so if you used real chocolate syrup, then it would have worked everyone will get the same outcome
+Olivia Discon That is an interesting hypothesis. I will have to try it out. Do you have a brand or suggestion for a non-artificially created chocolate syrup? I don't think I have found many other than melting chocolate myself.
+The Sci Guys that is actually a great question it is very hard these days to find real chocolate syrup with cocoa and no artificial flavors, so i would just research it
+Olivia Discon Nesqick is the type we used in the experiment. I don't think it's the artificial flavors that bled into the other layer. I think it was the colouring that was in the syrup.
Were all of the liquids the same temperature? If one was hot and another was cold, it's possible that the hot layer stayed on top of the cold layer (as hot liquids rise, just like how hot air rises) 😊
I need serious help......plz help me figure out how to stack those without mixing them......what is the key or secret? And by the way u guys r drinking awesome the experiment was a huge success and so educational I love to learn......
shawna remondet The key is the use a turkey baster or liquid syringe to slowly add the liquids on top of the next layer. If it's a liquid that isn't sticky, then you can try and pour it against the side of the glass to help slow it down, that way it has less of a change of mixing. I hope those tips help.
+Arpita Mulgund I wouldn't unless you know it won't react with anything else in the tower. We chose liquids that wouldn't have any adverse chemical reactions together.
I have a question, if you mix liquid A and B. Liquid B will float over liquid A, then you got another liquid C, if you mix it with liquid B, this one will float over liquid B. What will be the result if you mix the three liquids together?
afroditagbc It really depends on the liquids in question and if they are soluble with each other. If they aren't then in many cases the liquids will more or less separate back into layers. It can get sort of complicated but if you have something aqueous and two organic compounds that are immiscible with one another everything would eventually separate into distinct layers
Excuse me, you said that a liquid with a greater density than another liquid would sink to the bottom, but when we add water, alcohol, washing up liquid, golden syrup and vegetable oil, it will happen that the vegetable oil is in the lowest position but vegetable oil has lower density than water, it should be water with the higher density. can you tell me why? thank you
Hi Guys i love your videos, but just a quick note, at 3:55 i think that number should read 7.91 x 10^25 rather than 7.91 x 10^24. From one scientist to another i thought you wouldn't mind the correction..... keep on doing what your doing though, great job!
Wow! So amazing thank you so much for doing the video about this experiment it's helpfully for me to study science easier. Why I haven't found this before this is so good. // Sorry for my English skill it's not really good.
+Zarwuh LuwszYooh I don't think there would be a really easy way to separate them. The only thing that would come to mind would be to use the turkey baster to suck out each layer but you would probably still get some mixing.
My son has to have 15 layers of immiscible fluids for his science project. He found information regarding sugar water; that if more sugar is added, the more dense it is. Where in this tower should that be added? Thanks for your help!
+Amy S It depends on how much suger you add. Many of the layers in our tower like the syrups are close to what you would make with sugar. I would say it may need to be a bit of trial and error because it depends so much on how much sugar. I wouldn't test it on the full tower, but I would test it on a small volume of one of the layers and see if it sinks or floats, if it sinks then try a sample from the next layer down and repeat until you find the one it floats on.
isn't water less density than lamp oil? waiting for you to answer and help because i have a test later on density i want to sagest a video about viscosity thanks hope u answer
+Mohammed Ali lamp oil is less dense than water visit this site for more in formation: www.stevespanglerscience.com/lab/experiments/seven-layer-density-column/
+Mohammed Ali Maneet Nagra is correct about the oil and it's density. We do have a video on viscosity, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-f6spBkVeQ4w.html
Nelson Reynolds Walsh We discussed this a little bit and we didn't come up with a very specific answer. Generally, if two liquids are next to each other and are not able to dissolve into each other, like oil and water, they should stay separate indefinitely. If there are two liquids next to each other, like honey and maple syrup, which can mix, then those two will eventually combine into a single layer. It's just hard to say how long that it will take since it depends on a lot of factors. Generally, more viscous liquids will take longer to mix through diffusion.
+K Dog I would suggest you google the density of your specific brand of dish soap. Each dish soap is a little different especially between normal concentration and ultra concentration.
+Cody Perez Many of these liquids are very close in density. If you were to shake it then some of them would probably separate but a number of them would mix together. Like Chocolate syrup and milk.
+VainZ Back I am not sure there is a best. It depends on what the requirements are. If none than just pick the experiment that is the most interesting and that the 6th grader has the most passion for and then have fun with it and make sure to explain the concepts in a fun or interesting way. Then sprinkle a little wow factor
