What usually happens when two liquids meet - when you pour milk into a cup of coffee, add food coloring to water, or combine two kinds of juice, for example? They mix, right? Well, that's not always the case. You and your child might be amazed by the results of this fun experiment materials
Here are a few tips before you start the experiment:
Now let's get started. Carefully pour each of the liquids, one at a time, down the inside of the glass in the following order:
You should end up with five fairly distinct layers of liquid in the glass.
Each liquid should have stayed in a separate layer on top of the previous liquid.
The liquids in the experiment stay in separate layers because they all have different densities. Density is mass (weight) per unit of volume - for example, grams/mL. The densest liquids go to the bottom, and the least dense liquids, which are more buoyant, stay on top.
Some of the liquids in the experiment - such as water and detergent - will eventually dissolve into each other (mix together). That process is sped up if you stir the ingredients or cover the container and shake it, or if you originally poured the liquids on top of each other instead of down the side of the glass.
