Colour Column Drink

Make a layered density column drink to bring some colour to your afternoon! Just remember that drinks like these are a sometimes food, nice to enjoy occasionally as a special treat.

Ingredients

Juices - one thinner, one thicker
Food dye
Cordial
Water and/or coconut water
Fruit of your choice
Umbrella garnish
Straw garnish
Glass(es)
Medicine dropper

Method  

Step 1: Organise your juices and add some food dye to some for an extra punch of colour. Pouring each liquid into cups first may make things easier. 

Step 2: Pour a little cordial into a glass.  

Step 3: Tip your glass on the side, slowly pour the next densest juice down the side of the glass using a clean medicine dropper  

Step 4: Continue layering the liquids with the most dense at the bottom and the least dense at the top. Coconut water or tap water will likely be the least dense but you will need to test with which juices you have on hand. 

Step 2: Add some garnishes and admire the layers. 

Density is basically how much “stuff” is packed into a particular volume or amount. The density of a juice is often determined by how much sugar or fruit is in it – the sweeter or thicker the juice, the denser it is. If you had exactly 100ml of water and 100ml of water with sugar mixed into it, the sugary water would be more dense.

As an extra challenge you could set up a sensitive kitchen scale and weigh the same volume of each of your juices and cordials. Did the weight of the juice match up with the order of your colour column drink?
