- 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.
- Check up on a favorite stuffed animal with a stethoscope, syringe, and other handy vet tools. Explore animal anatomy by assembling organ and muscle systems. Play a "find the fracture" game using an x-ray lightbox and a set of animal cards. Learn to read cat and dog body language, and how vets understand animals when they can't talk.
- Aim, shoot, and score with this physics-friendly crate! Engineer an adjustable catapult and play a spirited game of basketball. Learn about the science of sports, and experiment with different angles and arcs until you're a hoop superstar.
- Open Froggie up, then use a pair of kid-friendly tweezers to explore the major internal organs that you and Froggie have in common — heart, lungs, stomach, and more. Then play a diagnosis game to figure out why Froggie isn't feeling well.
Froggie comes as a finished product, not a DIY building kit.
- 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!
- Mix together a witchy brew using citric acid and colored baking soda, use the pump to add water, then watch your cauldron bubble and boil in a creepy chemical reaction!
- 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.
