Step 3: Making the Layers
The first thing you pour in is your milk, on the bottom will be your milk, and on top will be the foam.
Then pour in your espresso shots right down the middle, you will notice it stays in the middle.
Then take out your chocolate syrup and pour it in until you can see it at the button, and then put a thin layer of chocolate on top of the foam. (make sure not to make it too thick or it will sink.)
And you have your finished product, a 5 layer macchiato.
This is a great example of density. Looking at this drink we can see that Chocolate Sauce is very dense, and the foam is not.
Density is a measure of how much mass is contained in a given unit volume (density = mass/volume). Put simply, if mass is a measure of how much ‘stuff’ there is in an object, density is a measure of how tightly that ‘stuff’ is packed together.
