Density Color Tower with Salt , Sugar & Water : Experiment

SALT+SUGAR Color Density  TOWER is a fun science experiment where kids can form different Color layers with just one component. They can use either salt or sugar to form this tower. They’ll also learn about the concept of density in this fun experiment.

Salt+Sugar 1

Step 1: Fill Each Glass with 200ml -300ml water.

Step 2: Take the pipette and drop 5 drops of food color in each glass.

Step 3: Add salt in each cup. 1 spoon in 1st cup, 2 spoons in 2nd cup and 3 spoons in 3rd cup.

Step 4:  Stir every cup until the salt dissolves.

Step 5: Now, take a straw and dip it in the first cup and cover the end with your thumb.

Step 6: Then dip it in the next solution, release the pressure.

Step 7: And you have your salt tower.

Step 8: You can also try to take the more dense solution first and then a less dense solution and see the solution changing the position.

Step 9: Try to make a solution using various concentration of sugar.

Working Principle of Salt+Sugar Tower :

In this experiment, you form a salt tower with three different layers. Each layer has a different concentration of salt solution. Since the concentration of each solution is different they don’t mix when sucked into the straw. Hence the Density of Each Concentration is Different.  The concentration/ Density varies which in turn makes the mass of the solution different. So the Lightest Color goes to the Top and Heaviest comes to the Bottom making different Cool Looking layers.

Quick Formula References : M(Mass)/Volume(V) = Density  . Here we see Mass is Directly Proportional to the Density .

When normal water is used, the colors get mixed. This happens because there is no variation in the concentration.

You can also try this with sugar by varying the concentration in each solution.
