Fireworks in a Jar

fireworks in a jar

Is there anyone in this world who doesn’t love enjoying fireworks? Fireworks are colourful and thrilling. However there are a few disadvantages of burning firecrackers which we will discuss later in this article. But here we will discuss about making fireworks in a jar?

Are you wondering how one can make fireworks in a jar? Here is an easy science experiment through which you can easily impress your friends and also perform it as a science trick during your school fair. Do not worry! This fireworks in a jar experiment doesn’t involve fire and punishing sounds, but there will be wonders of colours. In fact, this is a water fireworks experiment.

Try it yourself

You need:

  1. An empty jar
  2. Food Colour – Any two
  3. Warm water
  4. Vegetable oil
  5. Bowl

What next?

This water fireworks experiment has just three simple steps. However, as we are using warm water to produce fireworks in a jar, please do this experiment only under an adult’s supervision.

Step 1:  Take a bowl. Mix vegetable oil and food colour in it. However, you may notice that the food colour and oil doesn’t get mixed. Why the colour doesn’t mix with oil? We will see that later.

Step 2: Pour warm water and fill the jar about 3/4 full with warm water.

Step 3: Now take the bowl and pour the mixture to the warm water.

You will be amazed to see that the vegetable oil and colour mix this time and creates a wonderful fireworks effect inside the jar. Surely it is impressive to watch and show, but why this happens? If you want to know why this experiment really creates fireworks in a jar effect, see our logic session below…

Logic of fireworks in a Jar:

Hope you have enjoyed the fireworks in a jar experiment. Now hos the hot water could produce a fireworks effect on vegetable oil and colours? The fireworks effect of this experiment is based on a very simple concept – the density of liquids. We all know that the density of liquids can change their tendency to float or sink when mixing them together. Water is denser than oil, and naturally oil floats on water. When we try to mix food colour with oil, as food colours are water-based, they won’t mix well. The food colours will stay like colour balls in the oil.

After keeping the food colour and oil inside the jar, when you pour warm water, the water will stay at the bottom. We know that food colour is denser than oil. This lets the food colour sink and reach the water at the bottom. When food colour meets water, it creates a tiny explosion and we will see it as a firework.

What are the disadvantages of burning firecrackers?

Fire crackers are fun and entertaining, but they do have certain disadvantages too. Here you will find the major disadvantages of firecrackers.

1. Sound Pollution!

Most firecrackers produce enormous sound. By over using these sound producing firecrackers you are steeling someones right to sleep. You are not only disturbing your neighbouring human beings, but also disrupting the normal life of many living things around you.

2. Air Pollution

Whether sound producing or light producing, firecrackers give out a lot of smoke. When burnt on the public places, metallic particles in this smoke creates dense and foggy smog. This can trouble others vision, especially while driving, and also creates severe problems to breathing.

3. Fire Accidents

This is a real caution for you. Fire accidents are not uncommon when people use firecrackers. Some of the most deadly firecracker disasters that took many lives are listed in the article written by the editorial staff of WonderList. As they call it – perhaps the most devastating, Enschede Fireworks Disaster of 2000 killed eighteen humans and injured another 946.

While there are many more downsides of burning firecrackers, you have nothing to worry when performing our Fireworks in a Jar Experiment. However, make sure to handle warm water. We have many more experiments that demonstrates and explains the density of water. Try these experiments mentioned below.
