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.
Discover everything that eggs have to offer with Eggsperiments from the KiwiCo Store! Use the scientific method with a series of egg-based experiments that explore chemistry, physics, and biology.
Magnetic Slime(Ages 9-16)
Pull together a batch of magnetic slime!
Polymers are really big molecules, made up of lots and lots of smaller molecules joined together. They can make materials bouncy like a rubber ball, stiff like a plastic toy, or stretchy like a piece of gum. One great way to play around with polymers -- and to do some hands-on experimentation with chemistry in general -- is to make your own slime.
In this experiment, we uplevel your standard green goo to jet-black magnetic slime that will magically move and dance without you even touching it!
Follow along below or in our How to Make Magnetic Slime video tutorial!
Want to keep going? Contact Solution Slime (ages 9+) uses a completely different recipe to make the same kind of polymer, so it's a natural follow-up experiment!
Crystal Garden(Ages 5-16)
Growing crystals is such a magical experience but the long wait can be hard for younger kids. Fortunately, we've got a crystal garden that will grow overnight in your refrigerator so you can wake up to beautiful crystals tomorrow. Leave them clear or add a few drops of food coloring to make crystals in a rainbow of colors!
This project uses Epsom salts, which are safe to handle and available in almost any drugstore. (Just don't eat it, obviously!) Because these Epsom salt crystals grow so quickly and easily, this project invites experimentation. You can try using containers of different sizes and shapes, and test out how big the crystals get if you leave them to grow for longer or shorter periods of time.
Contact Solution Slime(Ages 9+)
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.
Want more slimey science fun without the hassle of gathering materials? Explore the science of thermochromism with Color Changing Slime from the KiwiCo Store!
Crystal Seashells(Ages 5-11)
Combine the excitement of the beach and the joy of science together with these amazing crystal seashells!
Do not worry if the beach is out of reach, local art stores tend to carry an assortment of shells and ocean decor.
Looking for more ways to unlock your inner chemist? Turn experiment time into playtime with the Chemistry Play Lab from the KiwiCo Store! Your young scientist has everything they need to experiment with color combinations, fizzy reactions, and more!
