Why "tinker and see"? Because the ideas that stick are the ones you find yourself. Every explorable here is built the same way: you get something to drag, flip, count, and break — and the big idea appears in your hands, before anyone tells you the answer.
Made by a dad and his 9-year-old test pilot. Inspired by Bret Victor's Explorable Explanations.
