How to…. make a Homemade Lava Lamp and the Science behind it.
Sitting in my living room is an orange Lava lamp which I love to sit and watch in the evenings.
The patterns that they make intrigue me!
There is some science behind how they work and it is interesting and fairly easy to understand.
Watch the video below and see how the Lava lamps are made.
They are very simple to make at home. All you need is an empty bottle, vegetable oil, water, 2 or 3 food colourings and some alka-seltzer tablets (these are fizzy indigestion tablets).
Listen to the explanation of how they work…..
This is a picture showing how Lava Lamp’s work.

So, the science behind the Lava lamp is density. The oil is less dense than the water so it floats on the top of the water and the water and oil seperate. An example of this is when there is an accident at sea and an oil tanker spills oil, the oil it spills floats on top of the water.
Density is the amount of matter contained in a specific volume, for example a block of wood is less dense than a block of iron the same size.
I am always intrigued as to how factories make so many items on their production lines and all the different proceses they use.
I have managed to find a video of how a famous Lava lamp making company make their Lava lamps at their factory.
Have a look it is fascinating!
