Fireworks in a Jar at the Farm

After seeing so many fireworks over the weekend, our pupils kept the theme going at the farm with a ‘fireworks in a jar’ experiment. Using oil, water and food colouring, they tried different colour combinations and watched to see what each jar would do.
Watching the colours fall
The oil floated in a layer above the water. The food colouring formed droplets in the oil, then sank into the water and began to spread. Pupils enjoyed watching the colours change as they moved through the jars.
Fireworks or lava lamps?
The jars all looked a little different. Some had trails of colour that looked like miniature fireworks, while others had bright layers and blobs that reminded us of lava lamps. The surprise was part of the fun, and pupils thoroughly enjoyed seeing how their colour choices turned out.
