10 Crazy Chemistry Experiments for Kids

Make a plain white flower glow in the dark in this simple experiment using household materials. All you need is a jar, a neon highlighter, and a flower!

Fizz, fizz, zoom! This baking soda experiment boat is easy to build and fun to race.

Discover more about the science of pressure with a Bottle Rocket kit from the KiwiCo Store! Assemble a launcher, rocket, funnel, and launch mixture to experience some extremely fizzy fun.

Take your winter decor to the next level with borax snowflakes!

This project made a fun science experiment and craft in one. The kids got to learn about solutions and see the "magic" of borax crystals forming and we got to make beautiful snowflakes to decorate our winter table centerpiece. The kids can't wait to experiment with different shapes and colors next time!Borax (sodium tetraborate) is a naturally-occurring mineral salt commonly used as a laundry booster or cleaner.

As with any other cleaning product, it should be kept away from children not under direct supervision of an adult.

Do not allow children to ingest Borax. If consumed, contact a poison control center immediately. Wash hands after play, as prolonged skin exposure may cause irritation.

Create fun that's clearly awesome with contact solution slime!

Slime is a super fun ooey gooey substance that is somewhere between liquid and solid. There are a lot of different ways to mix up slime, but this concoction uses contact solution to create an extra stretchy experiment.

Make a fiery black snake rise from the ground with this exciting experiment! Using simple household ingredients, learn how a burning mixture of baking soda and sugar can create a stunning carbon snake. Always be careful when conducting experiments involving fire. Be sure to only light the sand on a safe fireproof base in a well ventilated area. Keep water nearby as a precaution. Remember to tie back long hair and never leave flames unattended or unsupervised by an adult.

Use some household materials to plate your coins with copper! You can also try copper plating designs onto your coins!In this project, you’re going to do two things: put copper into a solution, and make that copper come out of the solution and stick to another piece of metal (the quarter). That first process is called “electrolysis” and the second is called “electroplating.” So how do you do those things? Well, their scientific-sounding names give you a clue: with electricity!

Electrolysis is a way to dissolve bits of metal into acidic liquids like vinegar. When you run electricity through vinegar, the vinegar helps to carry electricity from one side of the circuit to the other. Those bits of the vinegar react with the copper, making little bits of copper leave the positive side of the circuit and go into the liquid. You’ll see this happening when your solution turns blue.

Electroplating is a way to put those little bits of copper onto something else. The bits of copper are ionic, which means they have an electrical charge, like a balloon that you rubbed on your hair. And just like a charged-up balloon, ions love to stick to things! By giving them another electrified metal, they rush out of the solution and onto the metal’s surface. You’ll see this when your quarter starts to change colors. With just a little electricity, you can use electrolysis and electroplating to plate a quarter with copper. Does that make it look like a penny to you?

Want to see a chemical reaction in action? With this egg in vinegar experiment, we observed and followed a regular egg through a transformation to become a bouncy egg. You can too with just a few repurposed ingredients you may have around the house for Easter!

This experiment allows you to see how two common household materials react — eggshell and vinegar. When these materials come in contact, a (safe) chemical reaction takes place and creates new compounds. This easy experiment is great for children to do on their own, and fun to observe how the egg changes over time.
