Although we are not celebrating the 4th of July here, we had the chance to observe a beautiful firework today. Here. In our living room. Without any noise – even the cats stayed around and didn’t hide under the bed ;).
A few simple ingredients and tadaaa – we had our very own fireworks in a jar. Fireworks in a glass are so easy to make and a great preschool science starter project.
All you need to create your own holiday fireworks project is
- A glass or jar (the bigger the better…) full of water
- Oil (sunflower oil works great!)
- Food coloring in your favorite colors
- A little spoon or a dropper
How to make a firework in a jar:
- Add the oil to the jar of water. You want to get an oil layer of approx. 1 cm.
- Add 4-5 small drops of food coloring (if you add too much, you will get a big food coloring explosion in the jar ;)…), using the spoon or the dropper. Do not stir!
- Now sprinkle salt on top of the food coloring drops and enjoy!
When I tried it the first time, I added way to much food coloring and even poured some accidentally. However, the result was pretty impressive. A huge “color explosion” in red! It looked amazing! Maybe we can call it “How to make a color explosion in a jar”…
On the bottom of the jar you can see some oil & salt bubbles.
I really love to make fireworks in a jar and cannot wait to try it with my preschoolers next term. Let me know if you tried to make a firework in a jar and how it went!
