Fireworks in a jar is a fun science activity to do with kids of all ages. For younger children it’s a great way to discuss colour mixing and for old kids you can discuss density.
This science activity uses things you probably already have at home: a clear jar, water, oil and food colouring.
Steps
Fill your container ¾ of the way with warm water.
In a separate bowl, mix 4-5 tablespoons of oil and a few drops of food colouring.
Use a fork to mix the oil and food colouring together
Gently pour the oil mixture in the jar and then wait for the fireworks
