- Sharpen some pencils — and your engineering knowhow — with a pencil sharpener you built yourself!
- Explore bubble chemistry, and how the construction and physics behind your machine helps bubbles form. Experiment with different wand positions and bubble formulas to make bigger, better bubbles, and practice noting your observations like scientists do! Then take a stab at more at-home explorations, from concocting your own super bubble mix, to building a pipe-cleaner bubble wand, to practicing bubble tricks.
- Engineer a basic circuit, using your slime as a conductor to light up an LED (and a love of science!). Then conduct a series of electric experiments that showcase the science of switches, resistance, LED color-mixing, and more!
- Build a launcher that uses elastic power to shoot foam cannonballs. Contains everything you need to build a working launcher and matching mount.
- Create your own STEM-powered adventure at home, with this 5-pack bundle of some of our most popular Tinker crates. There's something here for every budding scientist, engineer, or innovator — from hands-on projects to amazing articles.
- Build a walking robot and experiment with mechanical motion!
- Engineer a hand-cranked, wooden automaton that makes a marble climb stairs. Explore the gears and cams that make the mechanics work.
- Produce an oxidation reaction that "eats" up aluminum foil. Test a voltmeter to learn about electric potential, and build a coin battery-powered LED light. Then put everything you learned together to engineer a clock that runs on just saltwater and strips of metal!

- Explore the science of thermochromism — with squishy slime that shifts color when it changes temperature!
- Wire up the motors, add the switch, and assemble your robot — all while exploring the science behind circuits and sensors. Customize your robot with one of two skins (a turtle or a beetle), then use the included flashlight to make it get a move on.
