What you’ll need
Gather these items to get started:
- Clear glass jar
- Water
- Vegetable oil (or any oil you have on hand)
- Food coloring (variety of colors)
- A spoon for mixing
For those who may not have vegetable oil, you can use canola oil or even olive oil in a pinch. The main goal is to have an oil that won’t mix with water.

Directions to follow
- Fill the Jar: Start by filling your clear glass jar with water, leaving some space at the top.
- Mix the Oil and Food Coloring: In a separate container, mix a few tablespoons of vegetable oil with several drops of food coloring. The food coloring will not dissolve in the oil.
- Create Fireworks: Slowly pour the colored oil mixture into the jar with water. Watch as the colors begin to swirl and explode like beautiful fireworks.
- Enjoy the Show: Take a moment to enjoy this colorful display!
Best ways to enjoy it
While this experiment stands alone as a fantastic visual treat, consider incorporating it into a themed science day with other fun activities such as making slime or baking a cake. You can even serve it alongside snacks like popcorn or colorful cupcakes for a delightful, festive atmosphere!
Storage and reheating tips
There’s no need to store this experiment, as it’s best enjoyed fresh. However, if you want to recreate the magic, you can easily set it up again. Just make sure to dispose of any leftover water and oil mixture safely.
Helpful cooking tips
- Make sure your oil and food coloring are well combined before pouring them into the water—this helps create that “fireworks” effect.
- For a longer-lasting display, try using more food coloring and a significant amount of oil to enhance the visual effect.
- Always supervise younger children during the experiment to keep things safe and fun.
Recipe variations
Change things up by trying out different colors or layering multiple colors for a more vibrant effect. You can also experiment with adding glitter or small confetti for an extra special touch that will delight all ages.
