Fireworks in a jar science experiment

Fireworks in a jar is a fun science experiment for kids that doubles as a craft activity. As parents, we’re always looking for something to do with our kids every 15 minutes, so why not try this one!

This activity will teach your children how oil and water don’t mix and add a colorful flair to the whole process.

What do you need to make fireworks in a jar?

Making fireworks in a jar is very easy and doesn’t require many supplies. All you need to make fireworks in a jar is:

• Water
• Oil
• Food coloring
• Water glass
• Small bowl
• Spoon

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!

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.

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!

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!

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

The trails that fall behind them will look like fireworks bursting in the sky!
