It can be tricky to keep kids busy during winter break — especially if you’re spending it in quarantine. To help, we pulled a mix of some of our favorite KiwiCo projects and DIYs. If you see a crate project you like, we recommend ordering right away so you get them before your kids go back to school!
Colorful Chemistry Ages 3+
Add a little color — and a whole lot of science — to your day! Learn about the scientific method, then put together a bubbly chemical reaction in your own fab chemistry lab.
Milk Swirl Experiment Ages 4+
Dip a drop of soap into milk to create a color explosion in your kitchen! Watch our video to see us make the colorful experiment from start to swirling color.
Crystal Chemistry Garden Ages 5+
Craft a colorful chemis-tree and garden using felt shapes and liquid watercolors. Then concoct a chemical solution that’ll make your garden grow fun and funky crystals over two days.
Bouncy Egg Experiment Ages 5+
This easy eggsperiment is great for children to do on their own! When you let an egg sit in vinegar, a (safe) chemical reaction takes place and creates new compounds. The result? A bouncy egg!
