We decided to make fireworks at home. Did you hear it right? Yes, you did. At home DIY explosives. But do not panic as they are as safe to make and can be played by little ones. In addition, you could teach density science to kids.
Does that sound exciting?
We decided to make two difference density science experiments to teach my daughters. Believe me, you will become a kid when you see the results. You will start loving to do this quite often. We did not buy any expensive things but used only the items available at home. The best part – you can do both these experiments in less than ten minutes.
Let’s start with the first one.
Shaving Cream, Water and Food Coloring Experiment
Clouds are always sound interesting and mysterious too for kids especially pre-schoolers. Today let’s clear the question marks on our kid’s faces when they see clouds and rain with our density science experiment.
This is a super fun and simple experiment to explain kids about the clouds formation and rain. Just fascinate our kids by bringing clouds and rain to our home since we cannot bring the real clouds though. Do not worry about the things we need to do this experiment. It sounds complex but it is very easy to do using a few commonly found ingredients in our home.
My children are eagerly waiting to watch the experiment instead of listening about it to be frank!! 🙂 Let’s begin our activity on density.
What all you need to create shaving cream rain clouds?
- Shaving cream
- food colouring (range of colours)
- eye dropper or syringe
- small container or glass cups

Instructions on How to create fireworks
Step-1 : Begin this activity by simply asking your child to fill the glass container we have taken. Make sure not to fill it completely and ask to leave some space (about an inch from the rim).
Step-2 : Now the exciting part to the kids is adding shaving cream 🙂 . But, kids need to be very careful while adding shaving cream on top of the water filled glass cup. Make sure not to add more shaving cream or do not make it thick since it takes very long time for the rain to fall. Also, waiting is the boring thing for kids while doing the experiment. So, do not make it too high.
Here, the water in the glass cup represents atmosphere and the shaving cream is the cloud.
Step-3 : Ask your kid to drop few drops of food colour to the foam already added to the water in the glass cup. Here, you can use a syringe or eye dropper to drop the food colour closer to the edge of the glass cup so that it falls quickly.
Step-4 : Here comes the most awaited step to our kids. My two little girls made their eyes big to watch the effect it is going to give 🙂
We need to wait for few minutes to see such a beautiful and exciting rain like effect because it depends on the size and thickness of the cloud.
Ask your kids to observe carefully!! The weight of the food colour or dye slowly starts to push the foam or cloud and falls down through the water creating a pretty and cool rain like effect. It doesn’t resemble the droplets like real rain but it gives something more like streaks of rain falling. BeautifulJ
At this point, you can take advantage and start discussion with your kids on colours and colour mixing. This helps to develop motor skills in your kids.
Tisha and Pritika loved trying this experiment with different colours and glass cups. They enjoyed watching streams of different food colouring fall like droplets through the foam and then swirl around the water. They also have some great questions but found it lovely experience. J
Science is always exciting, wonderful and fun for curious children and my children are not less to fall under that category to keep on trying different, simple and easy science experiments. That doubled my energy to explain them the same concept using different ingredients found in our home. This helps our children to become good at thinking and observing.
The main motto that encouraged me to do another experiment is “my younger daughter asked me, Mamma! Can you make it happen differently?” So, I decided to make them understand clearly in a different way using different ingredients. Let us get started without late.
Oil, Water and Food Coloring Experiment for Kids
This is not only a hands-on experiment but it would also be a thoughtful science lesson for your kids.
Materials we need
We only require a few ingredients to set up the density science experiment to learn more about density of various substances.
- Food Colour
- Plastic cups
- Glass cups
Procedure to follow
This activity is also pretty good to watch for kids. It teaches them more about the density concept and creates a ‘WOW’ factor for them.
Start by pouring a little amount of oil into a plastic cup until it reaches to one inch length from the bottom line of the cup. Then ask your kid to add a few drops of food colour (any colour of your choice) to the oil in the plastic cup. Mix it nicely using a fork.
Now ask again to fill the glass cup with water leaving some space (around one inch) from the top edge of the glass cup.
Let your kid to add the oil and food colour mixture to the water in glass cup. At this point, ask the children to observe carefully “what’s happening when we add oil mixture to the water?”
Oil and water does not mix up and the food colour drops gradually falls into the water pushing through the oil layer. Here, explain the kids clearly about ‘how density takes its role to push the food colour drops into the water?’
The amazing part for the kids is that a few minutes later after adding the food colour drops and oil mixture to the water, the food colour drops starts pushing into the water and forming a same gorgeous rain like effect like we observe in the above experiment. Great, isn’t it!? 🙂
My little ones also observed that the water and oil is not mixed up and they both separated forming a layer. You can explain kids the simple science behind this.
In between you can ask your kids to predict the changes that are going to happen during the experiment. You can also ask them to record the changes by drawing on a paper like what they see and observe while performing experiment.
Yes, I hope you all also agree that this is another such a beautiful experiment to explain density concept to the kids. I really encourage you all to try the above explained two experiments with your own children. Hope it’s going to be a great visual demonstration for you all too!! 🙂
However, just a note that we got struck several times as we did it quickly to understand that it went down before the fun began. Also, food color was more and hence it descended quickly. Finally, we got the trick of adding the solution slowly and allowed it to float on the top. The food color was suspending on the top of the oil.
Let the kids watch, observe and have fun the way ‘firework’ works!!!
