Stack seven different liquids in seven different layers. Anyone deserve to stack blocks, boxes, or books, however only those through a secure hand and also a small understanding the chemistry deserve to stack liquids. What if you can stack seven various liquids in seven different layers? Think that it as a science burrito!

EXPERIMENTMeasure 8 ounces that each form of liquid right into the 9 ounce section cups. You may want to shade each of the liquids to do a more dramatic impact in your column. Irradiate Karo syrup is simpler to shade than dark syrup. The just liquids that you may not have the ability to color are the vegetable oil and the honey.Start your pillar by putting the honey into the cylinder. Now, you will certainly pour every liquid progressively into the container, one at a time. It is really important to pour the liquids slowly and also into the facility of the cylinder. Make sure that the liquids execute not touch the sides of the cylinder when you space pouring. It’s it s okay if the liquids mix a tiny as you room pouring. The layers will always even us out because of the differing densities. Make sure you to water the liquids in the adhering to order:HoneyKaro syrupDish soapWaterVegetable oilRubbing alcoholLamp oilAs you pour, the liquids will certainly layer on top of one another. After ~ you pour in the liquids, girlfriend will have actually a seven-layer scientific research experiment – a science burrito!
HOW DOES it WORK?
The exact same amount the two different liquids will certainly have various weights due to the fact that they have various masses. The liquids that weigh much more (have a greater density) will certainly sink listed below the liquids that weigh less (have a reduced density).
You are watching: Density of dishwashing soap
|Dawn food Soap||1.06|
|Light Corn Syrup||1.33|
To check this, you can want to collection up a scale and also measure every of the liquids the you poured right into your column. Make sure that you measure up the weights that equal parts of each liquid. Friend should uncover that the weights the the liquids correspond to each various layer of liquid. For example, the honey will certainly weigh more than the Karo syrup. Through weighing this liquids, you will uncover that density and weight are very closely related.
** NOTE: The number in the table are based on data indigenous manufacturers for each item. Due to the fact that each manufacturer has its an enig formula, the densities might vary from brand to brand. You’ll an alert that follow to the number, rubbing alcohol have to float on optimal of the lamp oil, yet we understand from ours experiment that the desk lamp oil is the peak layer. Chemically speaking, desk lamp oil is nothing much more than sleek kerosene v coloring and also fragrance added. Walk every brand of lamp oil exhibit the very same characteristics? Sounds favor the foundation of a good science fair project.
The table reflects the densities that the liquids provided in the column as well as other common liquids (measured in g/cm3 or g/mL).

Density is basically just how much “stuff” is smashed right into a details area… or a comparison between an object’s mass and volume. Remember the all-important equation: thickness = Mass split by Volume. Based upon this equation, if the load (or mass) of other increases but the volume stays the same, the density has to go up. Likewise, if the massive decreases but the volume stays the same, the density has to go down. Lighter liquids (like water or rubbing alcohol) room less dense than heavy liquids (like honey or Karo syrup) and also so float on top of the an ext dense layers.
