Stack seven different liquids in seven different layers. Anyone deserve to stack blocks, boxes, or books, yet only those v a secure hand and a little understanding of chemistry have the right to stack liquids. What if you can stack seven different liquids in seven different layers? Think of it as a scientific research burrito!

EXPERIMENTMeasure 8 ounces that each type of liquid right into the 9 ounce portion cups. You might want to color each the the liquids to do a an ext dramatic effect in her column. Light Karo syrup is less complicated to color than dark syrup. The only liquids that you may not be able to color are the vegetable oil and the honey.Start your shaft by putting the honey right into the cylinder. Now, you will pour every liquid slowly into the container, one at a time. It is really important to to water the liquids slowly and also into the center of the cylinder. Make certain that the liquids execute not touch the sides of the cylinder when you are pouring. It’s okay if the liquids mix a tiny as you are pouring. The great will constantly even us out because of the varying densities. Make sure you to water the liquids in the adhering to order:HoneyKaro syrupDish soapWaterVegetable oilRubbing alcoholLamp oilAs girlfriend pour, the liquids will layer on optimal of one another. After you to water in the liquids, friend will have actually a seven-layer scientific research experiment – a scientific research burrito!
HOW DOES it WORK?
The very same amount the two different liquids will have various weights since they have various masses. The liquids that weigh more (have a higher density) will sink listed below the liquids that weigh much less (have a reduced density).
You are watching: What is the density of dish soap
|Dawn dish Soap||1.06|
|Light Corn Syrup||1.33|
To test this, you might want to set up a scale and measure every of the liquids the you poured right into your column. Make certain that you measure up the weights of equal sections of every liquid. You should find that the weights the the liquids exchange mail to each various layer of liquid. For example, the honey will certainly weigh much more than the Karo syrup. By weighing these liquids, girlfriend will uncover that density and also weight are very closely related.
** NOTE: The number in the table are based upon data indigenous manufacturers because that each item. Because each manufacturer has its an enig formula, the densities may vary from brand come brand. You’ll an alert that according to the number, rubbing alcohol need to float on top of the lamp oil, but we recognize from our experiment the the desk lamp oil is the peak layer. Chemically speaking, lamp oil is nothing an ext than polished kerosene with coloring and also fragrance added. Does every brand of lamp oil exhibit the exact same characteristics? Sounds favor the foundation of a great science same project.
The table mirrors the densities of the liquids supplied in the column as well as other typical liquids (measured in g/cm3 or g/mL).

Density is basically exactly how much “stuff” is smashed into a particular area… or a comparison in between an object’s mass and volume. Mental the all-important equation: density = Mass separated by Volume. Based on this equation, if the load (or mass) of other increases yet the volume continues to be the same, the density has to walk up. Likewise, if the massive decreases yet the volume remains the same, the density has to go down. Lighter liquids (like water or rubbing alcohol) room less thick than heavy liquids (like honey or Karo syrup) and also so rise on peak of the much more dense layers.
