How to do Fireworks in a jar science experiment
How to Make Water Fireworks
For sure, these aren't exactlyfireworks but they do resemble the real thing, only underwater! This is a great project for the kids at home or during class, to learn about colors, patterns and how various liquids react in water.
Fill the jar with water.Place the jar where everyone involved can see inside the side of the jar; this is where the best effect will occur.
Pour the vegetable oil into the cup.Add a few drops each of the different food colorings.
Use a fork to mix the colors into the vegetable oil.It won't dissolve, but that's part of the magic.
Have everyone sit or stand ready to see what happens.Remember, they must be able to see the sides of the jar with ease.
Pour the multi-colored oil into the water inside the jar.Watch what happens. There will be an explosion of color streams as the various colors separate away from the oil into the water, with all of the added liquids heading for the bottom of the jar.

- This is a project kids can do entirely by themselves, seated at tables or over the kitchen sink. Just be sure it's somewhere that it's okay to spill the food coloring, should the worst happen!
- The food coloring can only dissolve in water. It cannot dissolve in the oil. As the coloring drops with the oil, it will eventually get released from the oil and dissolve into the water.
