10 Crazy Chemistry Experiments for Kids

Turn an egg into a bouncy ball! Make a flower glow in the dark! Drop a quarter into a cup of water and pull it back out coated in copper! These crazy chemistry experiments may seem like magic tricks, but they're also great ways to give your emerging mad scientist a crash course in chemical reactions. 

  • Visual aid of how to complete Glow in the Dark Flower

    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!

  • Visual aid of how to complete Baking Soda-Powered Boat

    Fizz, fizz, zoom! This baking soda experiment boat is easy to build and fun to race. If you’ve ever dropped a fizzy tablet into a cup of water or made a baking soda volcano, you’ve made the same chemical reaction used here. But this time, we’re using that reaction to power a soda bottle boat, for a short distance at least.This is one baking soda experiment that is more fun with more room, so try this one in the bathtub. You can also experiment with the amount of baking soda and vinegar you add.

  • Visual aid of how to complete Borax Snowflakes

    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.

  • Visual aid of how to complete Egg Geodes
    Egg Geodes

    (Ages 9-16)

    Have you ever grown your own crystal geodes? Try this egg experiment and grow your very own borax crystals in a shell! Experiment with different borax concentrations and see how big your egg geodes can grow. 

  • Visual aid of how to complete Contact Solution Slime

    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.

  • Visual aid of how to complete Lava Lamp Science Project

    Have you ever seen a lava lamp? All of the colorful wax that rises and falls, bobbing around--it's mesmerizing! You've probably wondered how to make one. This is an easy science experiment that you can do at home to create your very own homemade lava lamp. And it only takes a few common household ingredients!

  • Visual aid of how to complete Carbon Sugar Snake
    Carbon Sugar Snake

    (Ages 12-16)

    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.

  • Visual aid of how to complete Copper Plated Coins

    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?

  • Visual aid of how to complete Egg in Vinegar Experiment

    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.

  • Visual aid of how to complete Invisible Ink with Lemon Juice

    Write secret messages to your friends and family and then let them decode it with any source of heat - like a candle or an incandescent light bulb!
