Sparkling Firework

This chemistry project for kids fizzes, pops, and sparkles – just like a real firework! With festive, patriotic colors and bubbling fun, this STEM project is perfect for celebrating the Fourth of July. Kids will love making the chemical reaction and watching their firework pop and crackle.

Video instructions for this STEM project are available here.

To make your sparkling firework, you will need:

Baking soda

Pop rocks

A packet of blue Kool-aid





A pipette

A paper plate

And here’s how it’s done:

Use your clay to make an outline of a shape on your paper plate. You can make a star, a diamond, a heart – whatever you’d like. Just make sure the shape is closed so all the ingredients will stay inside.

Mix up a little bit of baking soda and pop rocks, just enough to fill one layer of your shape. Give your plate a gentle shake to spread the mixture. Sprinkle on a layer of the Kool-Aid. Add confetti and glitter on top. You don’t need a lot of these ingredients for it to work!

Once you have your layers, it’s time to create the reaction! Use the pipette to add water and watch as your firework bubbles, sparkles, and fizzes! Can you hear your firework? Can you smell it?


Chemistry can be so fun! Send a picture or video of your project to The Winkle Crate on Instagram or Facebook. I’d love to see how yours turned out!
