How do you make fireworks with oil and water?

Since water and oil don’t mix, you can make fireworks in a jar by mixing food coloring into oil, then pouring the oil into a glass of water. As the food coloring sifts through the oil, it will then drop into the water and create a cool trail of color.

Here’s how to make fireworks in a jar with oil and water!

How to make fireworks in a jar - Celebrating with Kids

Step one: Fill water glass

Start by filling a glass 3/4 full with water.

Literally, that’s it for this step. Great job, you crushed it.

Step two: mix oil and food coloring

Pour about 2-3 tablespoons of oil into a small bowl.

Putting food coloring into bowl of oil

Next, drop 5-6 food coloring drops of a few different colors into the oil. We found that lighter colors look better than darker colors because the darker colors will change the color of the water faster and make it harder to see anything.

You can use a couple drops of dark, but stick to yellow, orange, pink or red for best results!

Mix up food coloring to make smaller drops

Then, gently stir to break up the drops that are sitting in the oil.

Step three: Pour oil mix into water

Finally, pour the oil into the glass of water! After a few seconds, watch the magic!

Pour oil mix into water

The oil and water will separate, but the food coloring drops will float through the oil and eventually leak into the water.
